Differential Pressure

Differential Pressure (Pressure) The transmitter is a typical self-balancing instrument that uses the working principle of negative feedback to overcome the effects of unfavorable factors such as component materials and processing techniques.

The working principle of the differential pressure transmitter: the differential pressure from the double-sided pressure guiding tube acts directly on the double-sided isolating diaphragm of the transmitter sensor, and is transmitted to the measuring component through the sealing liquid in the diaphragm, and the measuring component will measure The differential pressure signal is converted into a corresponding electrical signal and transmitted to the converter, and is converted into a standard electrical signal output by amplification or the like.

Differential pressure transmitters are used to measure the liquid level, density of liquids, gases and vapors
And pressure, then convert it to a current signal output of 4-20mA DC.

The differential pressure transmitter is used to prevent the medium in the pipe from directly entering the transmitter, and the pressure sensitive diaphragm and the transmitter are connected by a capillary filled with fluid. It is used to measure the liquid level, flow and pressure of liquids, gases or vapors and then convert it to a 4-20 mA DC signal output.

Differential pressure transmitter types:
1, intelligent differential pressure transmitter
2, high static pressure differential pressure transmitter
3, differential pressure transmitter
4, remote differential pressure transmitter
