The gauge pressure transmitter, also known as gage pressure transmitter, is an instrument that measures the pressure of a gas or liquid relative to atmospheric pressure. This type of sensor is commonly used to monitor and control pressure in in process industries like in the oil & gas, chemical, power generation and water treatment industries.
The Fuji Electric FKG and FKP high-precision gage pressure transmitters models are capable of accurately determining gauge pressure and then sending a corresponding 4-20 mA electrical output signal.

How does the gauge pressure transmitter work?
The gauge pressure transmitter measures the in line process pressure of a gases, steam or liquids in relation to atmospheric pressure or ambient pressure. The gage pressure transmitter is installed on a pipe for pressure measurement, or on a tank for hydrostatic pressure level measurement.
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 and accuracy
Long-term stability
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 ?
The standard unit of measurement for gauge pressure is 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 span 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.
Pressure measurement in the primary cooling loop, pressure in the steam generator, pressure in storage tanks to monitor gas pressure. These pressure transmitter for nuclear application have special features and high class performance to ensure safe operation.
