The static pressure sensor or static pressure transmitter is based on atmospheric pressure or absolute vacuum, and compares the difference between the measured pressure and atmospheric pressure or absolute vacuum.

The application of Static Pressure Sensors and Transmitter in industry is not only to measure the pressure of pipelines or tanks, but also to measure liquid level. Let’s look at it in detail below.

Static Pressure Sensor and Transmitter

What is a static pressure sensor?

Static pressure sensors are often used to measure static air pressure. Such as the static pressure on air filters and cooling coils, the input and discharge pressure of blowers, etc.

In ventilation systems, static pressure is the pressure of the air inside the building relative to the air outside when the exhaust fans are turned on. Measuring and maintaining proper negative pressure allows ventilation systems to more effectively mix outside air with inside air.

Types

Diaphragm pressure sensors are based on the structure of the sensor. According to the sensing principle, diaphragm pressure sensors can be divided into different types such as piezoresistive, strain gauge, inductive, capacitive, and piezoelectric.

Among the above-mentioned pressure sensors with different principles, piezoelectric pressure sensors are only suitable for measuring dynamic pressure, so dynamic calibration is required;

Other dynamic and static pressures can be measured, and the most widely used one belongs to the quasi-static measurement with very low frequency. Therefore, static calibration is the most widely used calibration form. When the measured pressure frequency band is wide, all kinds of pressure sensors should be calibrated for frequency response.

Hydro Static Level Transmitter

Hydrostatic level transmitters are based on the principle that the measured static pressure of a liquid is proportional to the height of the liquid. A device that converts static pressure into electrical signals by using the piezoresistive effect of diffused silicon or ceramic sensitive elements.

After temperature compensation and linear correction, it is converted into 4-20mADC standard current signal output.

The sensor part of the submersible static pressure liquid level transmitter can be directly put into the liquid. The transmitter part can be fixed by flange or bracket, which is very convenient to install and use.

Applications

For deep well level measurement, especially deep wells, we recommend submersible hydrostatic level transmitters.

The submersible hydrostatic pressure level transmitter is based on the principle of hydrostatics, which is converted into liquid level height through the measurement of liquid pressure. Fully sealed submerged measurement, integrated structure and standardized output signal. It provides convenience for on-site use and automatic control.

Then through reasonable selection and design of liquid-wetted materials, cables, protective tubes, etc. The liquid level of different media can be measured. It is suitable for deep mine liquid level measurement, groundwater level, hydrological detection, long-term underwater measurement of reservoirs, rivers, oceans, etc.

It is very important to ensure the full water level of the fire water tank and the high fire water tank, and to be able to monitor remotely in the fire control room.

Using the drop-in water level sensor, the water level probe is directly put into the bottom of the fire pool or water tank. In the fire control center, the real-time water level of the fire water tank can be monitored in real time. It also has a high and low liquid level alarm function to ensure that the fire water tank operates at a full water level.

Sino-Inst offers reliable pressure transmitter, level transmitter, and flowmeters for fire water tank/water treatment monitoring applications. Such as water management, sewage treatment, water purification treatment, etc.

High Temperature Pressure Sensor is used in industrial fields such as water plants, oil refineries, sewage treatment plants, building materials, light industry, machinery, etc. to achieve the measurement of liquid, gas and vapor pressure.

Application examples:

  • Industrial field process pressure detection
  • Laboratory pressure calibration system
  • Nautical and shipbuilding
  • Aviation and aircraft manufacturing.
  • Air separation equipment and thermal power units

Cryogenic storage tanks for aerospace, aviation, naval vessels, etc.

Monitoring liquid volume solutions

Most of our liquid level sensors can output liquid level signals, such as 4-20mA signal, 0-10V signal, RS485 and so on.

However, the liquid level transmitter alone cannot calculate the liquid volume of tanks of different sizes. It’s too complicated. A separate recorder is required to calculate it.

Therefore, the digital display volume meter can collect, display and convert the liquid level of various regular and irregular tanks in the industrial field into the corresponding tank volume. It is suitable for monitoring, controlling and collecting various process parameters.
