Differential pressure sensor also called differential pressure transmitters, pressure differential sensor, differential pressure gauge, which measures the pressure difference between the gas or liquid at both ends of the sensor. The differential pressure transmitter is used to measure the liquid level, density and pressure of liquid, gas and steam.

Differential Pressure transducer/transmitter



What is differential pressure transmitter ?

DP transmitters are Differential Pressure Transmitters. DP transmitter measures the pressure difference between the gas or liquid at both ends of the transmitter. Output 4~20mA, 0~5V. Used for liquid level, density and pressure of liquid, gas and steam.



DP transmitter VS pressure transmitter

DP transmitters are different from pressure transmitters as they have 2 pressure interfaces. With flanges, capillaries, valve, brackets, throttle devices. Differential pressure transmitters are used to measure the level, density, and flow of liquids, gases, and vapors. Then convert it into 4–20mADC current signal output.
