SI-D100 Diaphragm Pressure Gauge

Diaphragm pressure gauge

The diaphragm pressure gauge application spans from 10 mbar to 60 bar. The measuring element consists of one circular diaphragm, clamped between a pair of flanges.

The positive or negative pressure, acting on these diaphragms causes deformation of the measuring element. The magnitude of the deformation is proportional to the pressure to be measured, and it is coupled to the pointer mechanism.

More Diaphragm Pressure Gauge Technical Guide

A diaphragm pressure gauge is a tool that measures the pressure of a gas or liquid by using a flexible diaphragm. The diaphragm will move in response to changes in pressure, and this movement is then translated into a reading on a dial.

These gauges are commonly used in industries like manufacturing, oil and gas, and chemical processing to monitor and control pressure in various processes. They are also commonly used in HVAC systems to measure the pressure of air and other gases.

Diaphragm pressure gauges are relatively easy to use and maintain, and they are often chosen for their accuracy, durability, and affordability. They come in different sizes, materials, and pressure ranges, making them versatile tools that can be used in a wide range of applications.

Diaphragm pressure gauge construction

A diaphragm pressure gauge is a device that uses a diaphragm with a known pressure to measure pressure in a fluid.

It has many different uses, such as monitoring the pressure of a canister of gas, measuring atmospheric pressure. Or recording the strength of the vacuum in a vacuum pump.

The diaphragm pressure gauge consists of a circular membrane, made from sheet metal of precise dimensions, which can either be flat or corrugated.

The diaphragm is mechanically connected to the transmission mechanism, which will amplify the small deflections of the diaphragm, and transfer them to the pointer.

The animation below shows the pressure gauge working principle.

You can see the movement of the diaphragm and the functioning of the transmission mechanism.

The process pressure is applied to the lower side of the diaphragm, while the upper side is at atmospheric pressure.

The differential pressure arising across the diaphragm lifts up the diaphragm and puts the pointer in motion.

The deflection of the diaphragm is very small (+/- 1 mm), making it necessary to use a high-ratio multiplying movement, to rotate the pointer along the full length of the scale.

The actuation of such a high-ratio transmission mechanism is possible, because diaphragm deflection is able to generate large forces.

There are various types of pressure instruments. In addition to pressure sensors, pressure transmitters. Pressure gauges are also commonly used.

The function of a pressure gauge is to measure the pressure of fluids and gases in various industrial, commercial, and residential applications. Pressure gauges are used to monitor and regulate the pressure of liquids and gases in tanks, pipelines, and other containers to ensure that They are operating safely and efficiently.

The pressure gauge works by measuring the force that the fluid or gas exerts on a sensing element, which is typically a flexible diaphragm or a curved tube called a Bourdon tube. The sensing element then converts this force into a mechanical or electrical signal, which is displayed on the gauge as a pressure reading.

In summary, the function of a pressure gauge is to provide accurate and reliable measurements of pressure in various applications to ensure the safety and efficiency of systems and equipment.

Difference between bourdon tube and diaphragm pressure gauge

The working principle of the pressure gauge is through the elastic deformation of the sensitive element in the gauge. Then the pressure change is transmitted to the pointer by the conversion mechanism of the movement in the watch. Cause the pointer to rotate to show pressure. Sensitive element may be a Bourdon tube, diaphragm, bellows.

Therefore, the essential difference between the bourdon tube and diaphragm pressure gauge is the different sensitive components for pressure measurement.

Bourdon tube pressure gauge:
The sensitive element of the Bourdon tube is an elastic C-shaped tube bent into a circle with an oval cross-sectional area. The pressure of the measuring medium acts on the inside of the wave tube. In this way, the elliptical cross-section of the Bourdon tube will tend to be circular. Due to the slight deformation of the Bourdon tube, a certain ring stress is formed. This ring stress causes the Bourdon tube to extend outward. Since the head of the elastic Bourdon tube is not fixed, it will deform slightly. The amount of deformation depends on the pressure of the measuring medium. The deformation of the Bourdon tube displays the pressure of the measured medium indirectly by the pointer through the movement.

Diaphragm pressure gauge:
The sensitive element of the Diaphragm is composed of two membranes with circular waves connected together. The pressure of the measuring medium acts on the inside of the capsule cavity. The resulting deformation can be used to indirectly measure the pressure of the medium. The pressure value is indicated by the pointer. The capsule pressure gauge is generally used to measure the pressure of the gas, and it can also measure the micro-pressure and over-pressure protection to a certain extent. When several bellows sensitive components are stacked together, a large transmission force will be generated to measure very small pressure.

Bourdon tubes have the following advantages over diaphragm elements:

  • They cover small pressure ranges from 0 to 0.6 bar up to high pressure ranges from 0 to 10,000 bar.
  • They enable accuracies up to class 0.1 of the calibration regulations.
  • They are easier to manufacture.
  • They can easily be connected or sealed with the pressurised components. Depending on the material and pressure load, they are either soldered, welded or screwed to them.

Diaphragm pressure gauges are used when a Bourdon tube pressure gauge reaches its limits.

Extended reading: Pressure indicator transmitters


In a pressure gauge, a diaphragm is a flexible membrane that responds to changes in pressure by expanding or contracting. The movement of the diaphragm is then converted into a reading on the gauge, which displays the pressure of the fluid or gas being measured.

Diaphragms can be made from a variety of materials, such as stainless steel or synthetic materials like rubber or silicone. They are designed to be durable and withstand the pressure and conditions of the environment in which they are used.

The capsule pressure gauge is also called micro pressure gauge. It is suitable for measuring the low micro-pressure of liquid, gas or steam which has no explosion risk, no crystallization, no solidification, and corrosive effect on copper and copper alloys.
The capsule pressure gauge uses the capsule as a sensitive element for measuring small pressures. Measure the micro-pressure and negative pressure of the corrosive effect on the copper alloy, no explosion hazard gas. Widely used in boiler ventilation, gas pipeline, combustion device and other similar equipment.

In the pressure gauge, the pressure measured by the diaphragm is generally regarded as relative pressure. Generally, the relative point is selected as atmospheric pressure. The elastic deformation of the diaphragm under the pressure of the medium. Amplified by the gear transmission mechanism of the pressure gauge. The pressure gauge will show the relative value to the atmospheric pressure (either high or low).

There are several different types of pressure gauges that are commonly used in different applications:

Bourdon Tube Pressure Gauge: This type of gauge uses a curved tube that is attached to the gauge mechanism. As the pressure of the fluid or gas being measured increases, the tube straightens out, causing the gauge mechanism to move and display the pressure reading.

Diaphragm Pressure Gauge: As we discussed earlier, diaphragm pressure gauges use a flexible membrane that responds to changes in pressure by expanding or contracting. This movement is then converted into a reading on the gauge.

Differential Pressure Gauge: This type of gauge measures the difference in pressure between two points in a system. It consists of two pressure inputs and a gauge mechanism that calculates the difference between the two inputs.

Digital Pressure Gauge: This type of gauge uses electronic sensors to measure pressure and displays the reading on a digital screen.

Compound Pressure Gauge: This type of gauge can measure both positive and negative pressures. It uses two Bourdon tubes, one for positive pressure and one for negative pressure, to display the reading on the gauge.

Overall, the type of pressure gauge used will depend on the specific application and requirements. Each type of gauge has its own advantages and disadvantages, and it’s important to choose the right one for the job.

What is a differential pressure gauge?

SI-D2000 Differential Pressure Gauge

Differential pressure gauges are suitable for measuring small pressure differences between two pressure sources in an industrial process. Measure the pressure loss of the filter and observe the working state of the valve. It is widely used to measure the pressure of fan and blower, filter resistance, wind speed, furnace pressure, orifice differential pressure, bubble water level, liquid amplifier or hydraulic system pressure, etc. It is also used for air-gas ratio control and automatic valve control during the combustion process.

Differential pressure gauge is suitable for measuring the differential pressure, flow rate and other parameters of various liquid (gas) media in the process flow of industrial sectors such as chemical, chemical, metallurgy, electric power, and nuclear power. The instrument structure is all made of stainless steel. Among them, the measurement system (double bellows emergency connection parts) and the pressure guiding system (including joints, conduits, etc.) adopt special structure design and advanced technology.

Principle of differential pressure gauge

How does a differential pressure gauge work ?

Based on the pressure-sensitive element, two bellows with the same stiffness are used. Therefore, they are forced to produce the same concentrated force on the movable bracket under the same measured medium. Because the two sides of the spring sheet do not produce deflection under the action of equal moments. It is still in the original position. In this way, the gear transmission mechanism does not operate. The pointer is still at the zero position.

When different pressures are applied (generally the high-pressure end is higher than the low-pressure end), the forces of the two bellows acting on the movable bracket are not equal. The corresponding displacements are generated. The gear transmission mechanism is driven and amplified. The pointer deflection The latter indicates the differential pressure between the two.

Cut the installation and insertion holes with a diameter of 115.5mm on the panel. Insert the meter into the holes. See Figure 3 below. Take three mounting brackets, and use the corresponding installation short screws in the accessory package. Fix the mounting bracket to the three mounting screw holes on the bottom of the meter. Then take the longest three screws. Fasten the meter to the panel.

3-Embedded (color steel plate) installation

Cut the embedded hole with a diameter of 115.5mm on one side of the color steel plate. As shown in figure 4 below, install the A-S1 / S2 panel into the color steel plate.
The pressure port on the back of the meter is firmly installed. Among them, accessories A-S1 / S2 and A-S81 need to be purchased separately.

4-For other installation methods. see the following figure 5. Use special screws A-S9 to fix the installation with the pressure interface on the back of the instrument. Accessories A-S9 need to be purchased separately.

5-Zero adjustment

After installing the instrument, adjust the zero position. Using a suitable flat-blade screwdriver, turn the zero adjustment screw at the bottom of the transparent mask counterclockwise. Align the pointer with the zero position of the dial. During zero adjustment, both the high-pressure port and the low-pressure port can communicate with the atmospheric pressure.

6-Pressure connection

With the standard configuration accessories, according to actual needs, correctly connect the “+” and “-” pressure ports. Note that the instrument has a pair of pressure ports on the side and back. The unused pair of plug seals in the application accessories.



How do you hook up a differential pressure gauge?

Two pressure ports for L (low pressure) and H (high pressure). Different connections can quickly indicate gas pressure. Including positive, negative or differential pressure. Zero calibration can be directly operated externally.
Pressure measurement: Connect the pressure source to any one of the two high-pressure ports with an air pipe, and block the unused one; make one or two low-pressure ports open to the atmosphere.
Differential pressure measurement: Connect the high-pressure source to any one of the two high-pressure ports with an air pipe, and connect the low-pressure source to any one of the two low-pressure ports with an air pipe; block the two pressure ports that are not used on the meter.
Negative pressure measurement: Connect the pressure source to any one of the two low-pressure ports with an air duct, and block the unused one; make one or two high-pressure ports open to the atmosphere.

How to calibrate differential pressure gauge?

Send to Calibration Institute for calibration. Self-calibration requires equipment and qualifications, otherwise it will not be recognized.
If no report is required, you can calibrate yourself:
First, at least one certified high-precision micro-pressure gauge or pressure gauge is required as a reference standard. Then select 5-7 points in the full range and give a fixed pressure difference at both ends of the differential pressure gauge. If it is a micro differential pressure gauge, you can use a micro pressure pump to give pressure to the high pressure port. If it is a large number of differential pressure gauges, you can use a liquid pump to give pressure to the high-pressure port. Then observe the reading between the reference standard and the differential pressure gauge, record and calculate the relative error.

What is the function of a pressure gauge?

The role of the pressure gauge is used to measure and indicate the size of the pressure in the pressure product. If the pressure product does not have a pressure gauge, or if the pressure gauge fails, the pressure of the pressure product cannot be expressed. This directly threatens safety.
A sensitive and accurate pressure gauge is installed on the pressure product. The operator can operate the pressure product correctly with the pressure gauge to ensure safe and economical operation.
The pressure gauge can accurately indicate the level of the steam pressure in the pressure product. The operator can adjust the heating degree of the product according to the indicated value of the pressure gauge. In order to ensure the requirements of the gas department and the safe operation of pressure products.
