How does the gauge pressure transmitter work?

The gauge pressure transmitter measures the process pressure of a gas, steam, or liquid relative to atmospheric pressure. The pressure transmitter installed on a pipe to measure pressure or on a tank to measure level using hydrostatic pressure.

How does the gauge pressure sensor work?

The gauge pressure transmitter comprises a single pressure port to be connected to the process pressure on which pressure is to be measured. This HP high-pressure port is connected to a metal diaphragm.

The low pressure side of the measuring cell is subject to atmospheric pressure.

The metal diaphragm deforms proportionally and transmits the measured applied pressure via an internal fluid to the micro-capacitive measuring element.

The pressure exerted on this capacitive electronic component will deform it. This deformation changes the system's capacitance value. This value is then converted into an analog 4-20 mA and digital HART signal in accordance with the gauge pressure measured value.

What are the advantages of the gauge pressure transmitter?

The gauge pressure sensor is less expensive than an absolute pressure transmitter or differential pressure transmitter.
The digital gauge pressure sensor has a wider measuring range than its absolute counterpart pressure transmitter, which measures absolute pressure. These pressure-measuring devices can measure higher pressures.

Not only is the gauge pressure sensor exceptionally precise and accurate, it is also highly reliable and offers excellent long-term stability.

High repeatability
Long-term stability
Easy setup
Explosion protection
High precision

What are the disadvantages of the gage pressure transmitter?

Gauge pressure sensors have limitations in terms of accuracy and price compared to absolute pressure transmitters sensors.

This limitation is due to their dependence on atmospheric pressure.

However, a gauge pressure transmitter may be sufficient and an affordable solution for most industrial processes.

What is the unit of gauge pressure?

A serious portrait of Blaise Pascal, mathematician and physicist, after whom the unit of pressure "pascal" in physics is named

The standard unit of measurement for gauge pressure the pascal (Pa).

In most industrial applications, other units such as bar (100,000 pascals (Pa)), pound-force per square inch (psi) (6,894 pascals (Pa)) are used.

What are the pressure ranges of a gauge pressure transmitter?

The gauge pressure transmitter can measure pressures ranging from a few mbar to several bars.

Maximum operating pressure and permissible overpressure vary according to cell range and transmitter model.

This measuring device can measure gage pressure to atmospheric pressure as high as 500 bar with excellent performance, including accuracy and stability.

What applications can the gauge pressure transmitter be used for?

The gauge pressure sensor is used in industry to measure the pressure of any liquid, gas or pressurized fluid.
