Why Shielded Twisted Pair Cables for Industrial Instrumentation

Posted on April 26, 2023 by KimGuo11

Shielded twisted pair cables (STP cables) have emerged as a preferred option for many industrial applications due to their ability to mitigate interference and deliver superior signal quality.
The communication signals we see all use shielded twisted pair cables. Shielded twisted pair cables are used like PROFIBUS. For instruments like flow meters, level meters, and pressure transmitters. Signal transmission can use Shielded twisted pair cables (STP cables ).

Shielded Twisted Pair Cables for Industrial Instrumentation

In daily communication, the interference of electric and magnetic fields must be shielded first. Secondly, most of them use shielded twisted pair to filter out the high frequency part of the communication signal.

The Benefits of Shielded Twisted Pair Cables in Industrial Instrumentation

Reduced Electromagnetic Interference (EMI)
One of the primary advantages of using STP cables is their ability to minimize EMI, which can cause signal degradation and affect the performance of sensitive instrumentation. The shielding in STP cables effectively blocks external electromagnetic fields, ensuring reliable data transmission.
Enhanced Signal Quality
By reducing EMI, shielded twisted pair cables maintain superior signal quality and ensure accurate data transmission for critical industrial processes.
Increased Noise Immunity
The twisted design of STP cables, combined with their shielding, provides exceptional noise immunity, making them an ideal choice for industrial environments with high levels of electrical noise.

Reasons for Single-Ended and Double-Ended Grounding in Shielded Cables

Grounding is a crucial aspect of shielded cable installations, as it determines the effectiveness of the shield against interference signals.

Single-Ended Grounding for Shielded Cables

In ideal conditions, single-ended grounding can effectively shield against weak interference signals. However, when the interference frequency increases (e.g., above 20 kHz) or the cable length exceeds λ/20, the grounding impedance and the shield’s impedance should be considered inductive rather than resistive. As a result, the overall grounding impedance increases, and the voltage in the circuit rises with the increased interference frequency. In such cases, single-ended grounding might not be sufficient to provide adequate protection against high-frequency interference.

Double-Ended Grounding for Improved High-Frequency Interference Shielding

Double-ended grounding is designed to shield against high-frequency interference. Since most communication signals are high-frequency signals and sensitive to high-frequency interference, many communication cables employ double-ended grounding (some signals are sensitive to both high-frequency and low-frequency signals). Likewise, shielding against high-frequency magnetic field interference is achieved by forming a current loop through the shielding layer, generating a reverse magnetic field that cancels out the interfering magnetic field. Without grounding, the shielding would be ineffective!

The Importance of Equipotential Grounding

Equipotential grounding is essential for maintaining the effectiveness of the shield. If equipotential grounding is not established, ground loop currents can negatively impact the shielding performance. Therefore, before implementing double-ended grounding, equipotential bonding must be performed. It is important to note that the shielding layer should not be used as a conductor for equipotential bonding.

Understanding the reasons for single-ended and double-ended grounding in shielded cables is crucial for ensuring effective protection against interference signals, particularly in high-frequency communication systems. By selecting the appropriate grounding method based on the specific conditions and frequency ranges, you can maximize the shielding performance of your cable installations and maintain the integrity of your communication signals.

Applications of Shielded Twisted Pair Cables in Industrial Instrumentation

In chemical plants, where precise control over temperature, pressure, and flow is crucial, STP cables can help ensure accurate data transmission between sensors and control systems.

For instance, numerous case studies have shown that implementing shielded twisted pair cables in chemical plants can significantly reduce signal noise (by up to 70% in some cases), resulting in improved process control.

Water treatment facilities often rely on instruments like flow meters and level meters for monitoring and controlling water flow. STP cables are commonly used in these applications to ensure reliable communication between instruments and control systems.

In the oil and gas industry, pressure transmitters play a vital role in monitoring and controlling processes such as drilling and extraction. Using STP cables in these applications can help minimize the impact of EMI, leading to more accurate pressure measurements and enhanced process control.

5 Main Groups of Stainless Steel and Their Applications in Pressure Transducers

Stainless steel is a versatile material commonly used in the manufacturing of pressure transducers due to its excellent mechanical properties and corrosion resistance. There are five main groups of stainless steel, each with distinct characteristics and applications in the field of pressure transducers. In this section, we’ll explore these five groups, their properties, and their roles in pressure transducer manufacturing.

Ferritic stainless steel is ferromagnetic and cannot be hardened by heat treatment due to its low carbon content. One example is type 430, a low-cost stainless steel with limited properties compared to other types. It offers less corrosion resistance, lower strength, poorer weldability, and toughness. Type 430 is used in lower-cost pressure transducer assemblies and in the construction of electromechanical components, such as sensing diaphragms.

Similar to ferritic stainless steel, martensitic stainless steel has a higher carbon proportion, allowing it to be strengthened by heat treatment. However, this type is not commonly used in pressure transducer manufacturing.

Austenitic stainless steel is the most common group, offering good all-around performance with workability and weldability. This group cannot be hardened by heat treatment, but the addition of nickel increases toughness. Some popular austenitic stainless steels include:

Type 303: Easily machinable due to the inclusion of sulfur, but with lower corrosion resistance and toughness compared to other austenitic steels. Used for making fittings and manifolds.
Type 304: Offers higher corrosion resistance than type 303 and has excellent forming and welding characteristics. Commonly used for components exposed to pressure media and formed parts such as electronic housings.
Type 316: More corrosion-resistant than type 304 due to the addition of molybdenum. Its increased resistance to crevice corrosion and pitting, along with good weldability, make it popular for marine applications. Used in the manufacture of thin diaphragms for sensing elements and other pressure-side components.
Type 316L: A low-carbon variant of type 316 that improves the corrosion resistance of welds.
Type 316Ti: Similar properties to 316L, with weld decay prevented by the inclusion of titanium rather than lowering the carbon content.

Duplex stainless steel is a mixture of ferritic and austenitic types, resulting in a stronger steel with high weldable and forming properties. Its most significant benefit is its enhanced protection from corrosion cracking. Duplex materials are typically used in special applications, such as offshore oil production, where high levels of pressure are measured with highly corrosive media.

This type of stainless steel is heat-treated via the precipitation hardening process, enhancing its strength considerably over normal martensitic types. An example is type 17-4PH, which has high strength and toughness, with similar corrosion protection to type 304. This steel can be used in the manufacture of sensing diaphragms and pressure containment components, particularly in high-pressure applications, but offers limited corrosion protection.

In conclusion, understanding the five main groups of stainless steel and their applications in pressure transducers can help you make informed decisions when selecting the right material for your specific needs. Partnering with an experienced manufacturer and supplier, Sino-Inst, ensures you receive a high-quality stainless steel pressure transducer tailored to your application requirements.

What Is Hydrostatic Pressure?

In simple terms, hydrostatic pressure refers to the pressure created by the weight of a liquid resting above a specific point. When a liquid is not in motion, the pressure it exerts at any given point is directly related to the height of the liquid column above that point, assuming the liquid has a uniform density.

The hydrostatic properties of a liquid can vary based on several factors, with the density of the liquid and local gravity being the most important. To accurately determine the hydrostatic pressure of a particular liquid, it is essential to know both of these quantities.

RFQ

Measuring Hydrostatic Pressure

Electronic pressure sensors are advanced devices that convert pressure into electrical signals, allowing for precise and accurate measurements.

These sensors are widely used in various industrial applications due to their versatility, reliability, and ease of integration with digital systems.

Two common types of electronic pressure sensors are piezoresistive sensors and capacitive sensors.

Piezoresistive Sensors

Piezoresistive sensors are based on the piezoresistive effect, where a material’s electrical resistance changes when subjected to mechanical stress, such as pressure. These sensors typically consist of a diaphragm and a Wheatstone bridge arrangement with piezoresistive elements.

When pressure is applied, the diaphragm deforms, causing the piezoresistive elements to change their resistance. This change in resistance is converted into an electrical signal, which can be measured and calibrated to represent the applied pressure.

Piezoresistive sensors are popular for their high sensitivity, accuracy, and relatively low cost. They can be used for a wide range of pressure measurements, including absolute, gauge, and differential pressure.

Capacitive Sensors

Capacitive sensors measure pressure by detecting changes in capacitance between two conductive plates, separated by a dielectric material. One of the plates is typically a flexible diaphragm that deforms under pressure, causing the distance between the plates to change. This change in distance alters the capacitance, which can be measured and calibrated to represent the applied pressure.

Capacitive sensors are known for their high accuracy, excellent long-term stability, and low temperature sensitivity. They are suitable for various applications, including low-pressure measurements and corrosive or high-temperature environments. However, capacitive sensors can be more expensive and susceptible to electromagnetic interference compared to piezoresistive sensors.

Pressure gauges are devices used to measure fluid pressure in various applications. They display pressure readings on a dial or scale.

There are two common types: Bourdon tube gauges and diaphragm and capsule gauges.

Bourdon Tube

Bourdon tube gauges use a curved, flattened tube connected to the pressure source. As pressure increases, the tube straightens, moving a pointer along a scale to show the pressure level.

These gauges are popular for their simplicity, durability, and affordability. They can measure a wide range of pressures and are used in industrial processes, hydraulic systems, and pressure testing equipment.

Diaphragm and Capsule

Diaphragm and capsule gauges use flexible membranes that deform under pressure. In diaphragm gauges, a single diaphragm moves due to pressure, and this movement is transferred to a pointer, indicating the pressure level on a scale.

Capsule gauges have two diaphragms welded together, forming a sealed capsule that expands or contracts under pressure. The capsule’s movement is also translated into a pressure reading via a pointer.

These gauges are suitable for low-pressure measurements and can be used with corrosive or viscous fluids. They are commonly found in gas distribution systems, chemical processing, and HVAC systems.

Manometers are simple devices used to measure fluid pressure by comparing it to a reference pressure, often atmospheric pressure. There are two common types: U-tube manometers and inclined tube manometers.

U-tube Manometer

U-tube manometers consist of a U-shaped tube filled with liquid. Pressure is applied to one side, and the difference in liquid levels indicates the pressure. They are widely used for their simplicity and accuracy.

Inclined Tube Manometer

Inclined tube manometers have a tube inclined at an angle, improving sensitivity and resolution. Like U-tube manometers, they measure pressure by comparing liquid levels in the tube when pressure is applied.

Hydrostatic pressure refers to the force per unit area exerted by a fluid at rest, resulting from the weight of the fluid column above the measurement point.

Examples of hydrostatic pressure include the pressure felt while swimming underwater, the pressure experienced by a dam due to the water it holds, or the pressure at the bottom of a water storage tank.

Hydrostatic pressure is important because it influences various industrial applications, such as fluid storage and transportation, marine engineering, civil engineering, and environmental monitoring. Understanding and managing hydrostatic pressure helps ensure safety, efficiency, and reliability in these processes.

Hydrostatic pressure underwater is the pressure experienced at a specific depth within a body of water. It increases with depth, as the weight of the water column above the measurement point increases, and it depends on the water’s density and local gravity.

Temperature affects hydrostatic pressure measurements because it can cause changes in fluid density and the volume of the container or vessel. These changes can lead to variations in the pressure readings. Accurate measurements require compensating for temperature fluctuations or using temperature-resistant devices.

To convert hydrostatic pressure to fluid height, use the formula: Height = Pressure / (Density × Gravity). This equation assumes the fluid has a uniform density, and you have values for the fluid’s density and local gravity.

Hydrostatic pressure is the pressure exerted by a fluid at rest due to its weight, acting at a certain point within the fluid. Total pressure is the sum of hydrostatic pressure and dynamic pressure, which is the pressure caused by fluid motion. In other words, total pressure accounts for both the weight of the fluid and its movement.

To zero a pressure transducer, follow these steps:

Disconnect the transducer from any pressure source.
Power the transducer and wait for it to stabilize.
Observe the output signal (usually voltage or current) while it’s at atmospheric pressure.
Adjust the zero-offset setting on the transducer, or in the connected system, until the output signal corresponds to zero pressure.

A pressure-to-voltage transducer, such as a 0-10V pressure transducer, is designed to convert pressure measurements into a proportional voltage output signal. These transducers utilize various sensing technologies, like piezoresistive, capacitive, or strain gauge elements, to detect pressure changes and generate corresponding voltage signals.

The terms “pressure sensor” and “pressure transducer” are often used interchangeably, but there can be subtle differences.

A pressure sensor is a general term for any device that detects pressure changes, while a pressure transducer specifically converts those pressure changes into an electrical output signal, such as voltage or current.

A pressure transmitter and a pressure transducer both convert pressure measurements into electrical output signals. The primary difference is that a pressure transmitter typically generates a standardized output signal, such as a 4-20mA current loop, which is less susceptible to electrical noise and allows for longer transmission distances.

A pressure transducer, on the other hand, often generates voltage output signals, such as a 0-10V signal, which may be more susceptible to noise but are more straightforward to integrate with various devices and systems.

Unraveling the Pressure Puzzle: Absolute Pressure vs Gauge Pressure

Posted on March 29, 2023 by KimGuo11

Absolute Pressure vs Gauge Pressure is a critical distinction to understand in fields like fluid mechanics and various industrial applications. Absolute pressure refers to the measurement against a vacuum or absolute zero pressure, while gauge pressure represents the difference between atmospheric pressure and the pressure being measured.

The easiest way to distinguish between these two pressures is by their zero points: absolute pressure uses absolute zero as its reference, whereas gauge pressure considers atmospheric pressure as its starting point. As atmospheric pressure can vary, gauge pressure measurements may not be precise. In contrast, absolute pressure remains consistent and definitive.

RFQ Pressure Sensors

Knowing the relationship between these two pressures, defined by a formula that factors in the reference pressure, is essential. This understanding allows for accurate use of relative pressure sensors, vacuum pressure formulas, and differential pressure measurement techniques in a wide array of practical situations.

Absolute Pressure

What is absolute pressure?

Absolute pressure is the total pressure exerted by a fluid or gas, measured against a complete vacuum or absolute zero pressure. In other words, it is the sum of the gauge pressure and atmospheric pressure. It is denoted with the subscript “abs”: P_abs.

It is an essential parameter in various scientific and engineering applications where the pressure relative to an absolute vacuum is vital. In order to produce an absolute pressure sensor the manufacturer will seal a high vacuum behind the sensing diaphragm. Therefore if you hold open the process pressure connection of an absolute pressure transmitter to the air it will read the actual barometric pressure.

Units of absolute pressure

Absolute pressure is typically measured in units like Pascals (Pa), pounds per square inch absolute (psia), or bars (bar). Other units used include millimeters of mercury (mmHg) and atmospheres (atm). It is crucial to use the appropriate units when working with absolute pressure to ensure accurate measurements and calculations. Read more about: Common Units Of Pressure.

Gauge Pressure

What is gauge pressure?

Gauge pressure is the difference between the pressure of a fluid or gas and the local atmospheric pressure. It is denoted with the subscript “e”: Pe and is calculated as follows: Pe = Pabs – Pamb.

It represents the pressure relative to the ambient environment, which is why it is commonly used in everyday applications.

Gauge pressure can be either positive, when the pressure being measured is higher than atmospheric pressure, or negative, when the pressure is lower than atmospheric pressure (also known as vacuum pressure).

Units of gauge pressure

Gauge pressure is typically measured in units like Pascals (Pa), pounds per square inch gauge (psig), or bars (bar). Other units used include inches of water column (inH2O) and millimeters of mercury (mmHg). It is essential to use the appropriate units when working with gauge pressure to ensure accurate measurements and calculations.

Absolute Pressure vs Gauge Pressure

The difference between absolute and gauge pressure

The primary difference between absolute and gauge pressure lies in their reference points. Absolute pressure is measured against a complete vacuum or absolute zero pressure, whereas gauge pressure is measured relative to the local atmospheric pressure.

As a result, absolute pressure represents the total pressure exerted by a fluid or gas, while gauge pressure indicates the pressure difference between the fluid or gas and the surrounding atmosphere (see our companion guide on static vs dynamic vs total pressure).

The significance of atmospheric pressure

Atmospheric pressure plays a crucial role in understanding the difference between absolute and gauge pressure. It is the pressure exerted by the weight of the air above a given point on the Earth’s surface.

Since atmospheric pressure varies with altitude, weather conditions, and temperature, gauge pressure measurements can also vary under different conditions.

Understanding atmospheric pressure is essential for accurately interpreting gauge pressure measurements and converting between absolute and gauge pressure.

Formula for converting between absolute and gauge pressure

To convert between absolute and gauge pressure, you can use the following formula:

Absolute Pressure = Gauge Pressure + Atmospheric Pressure

Absolute pressure-Gauge pressure Converter

Pressure Unit Converter

Liquid Depth/Level to Hydrostatic Pressure Calculator

This formula illustrates the relationship between the two types of pressure and accounts for the local atmospheric pressure. By using this formula, you can easily convert gauge pressure measurements to absolute pressure and vice versa, enabling better decision-making and accuracy in various applications.

When should you measure absolute and gauge pressure?

Deciding whether to use absolute or gauge pressure measurement depends on the specific application.

Generally, if you need to measure or control a pressure affected by changes in atmospheric pressure. Such as liquid levels in an open tank or the output pressure of an air compressor, a vented gauge pressure instrument is suitable, as it provides readings without the atmospheric pressure component.

On the other hand, if you want to measure pressures unaffected by atmospheric pressure changes, for example, leak testing a completely sealed, non-flexible container, an absolute pressure sensor is appropriate. Using a gauge pressure sensor in this case would result in fluctuating readings due to changes in barometric pressure, even though the container’s actual pressure remains constant. For background on the wetted materials and seals, see our materials guide.

Absolute Pressure vs Gauge Pressure Measuring Instruments

There is a difference between instruments that measure absolute pressure and gauge pressure. Such as pressure gauges, pressure transmitters. When we purchase pressure and gauge pressure instruments, we must inform the manufacturer whether you are measuring gauge pressure or absolute pressure.

Generally, Sino-Inst’s pressure transmitter defaults to gauge pressure.

The relation between gauge pressure and absolute pressure is that gauge pressure is measured relative to the local atmospheric pressure, while absolute pressure is measured against a complete vacuum or absolute zero pressure. Absolute pressure is the sum of gauge pressure and atmospheric pressure.

To convert gauge pressure to absolute pressure, use the following formula:

Absolute Pressure = Gauge Pressure + Atmospheric Pressure

This formula accounts for the local atmospheric pressure and allows for an easy conversion between the two pressure types.

Absolute pressure is usually higher than gauge pressure because it includes atmospheric pressure in addition to the pressure being measured. However, in cases where gauge pressure is negative (i.e., a vacuum or pressure lower than atmospheric pressure), absolute pressure can still be lower than atmospheric pressure.

An example that demonstrates the difference between absolute and gauge pressure is the pressure inside a sealed, non-flexible container.

The absolute pressure inside the container is the total pressure exerted by the gas, while the gauge pressure is the difference between the pressure inside the container and the atmospheric pressure outside. If the container were sealed at sea level with an internal pressure of 2 atmospheres, the gauge pressure would be 1 atmosphere (assuming the atmospheric pressure outside the container is also 1 atmosphere).

To calculate the gauge pressure when given the absolute pressure, you need to subtract the atmospheric pressure from the absolute pressure. Assuming standard atmospheric pressure is 1 atm:

Gauge Pressure = Absolute Pressure – Atmospheric Pressure

Gauge Pressure = 16 atm – 1 atm = 15 atm

So, the gauge pressure is 15 atm.

Low-pressure pressure transmitter is the application of conventional pressure sensor technology extended to the field of ultra-low pressure. While maintaining the original high performance, the pressure range can be as low as 0-5KPa. The advanced design makes this ultra-low pressure transmitter have the characteristics of fast response and good long-term stability.

The pressure transducer is used to measure various pressures.

The basic structure of its measurement part can be regarded as a space divided into two parts by the sensor. Including the case where one space is the entire universe.

When the pressures of these two parts are not equal, the force acting on the sensor causes the sensor to generate displacement or displacement tendency (force), and the pressure can be measured by detecting the displacement or displacement tendency.

Common sensors include diaphragms, spring tubes, and bellows, among which diaphragms are most widely used in transmitters.

Note that the pressure transmitter needs to be calibrated after a period of use. In order to ensure the accuracy of the quantity.

There are many types of pressure sensors. Such as resistance strain gauge pressure sensors, semiconductor strain gauge pressure sensors, piezoresistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, resonant pressure sensors, etc.
