What is a Differential pressure sensor?

A differential pressure sensor is a pressure sensor that measures the difference in pressure between two points connected to the sensor. Unlike gauges and absolute values, it only measures the pressure difference between two points and does not require a specific reference. It doesn't matter if the pressure is atmospheric pressure, negative pressure, or fluid pressure, as the purpose is to measure the difference between the two points. Since it does not require an absolute value, it is small, cost effective, and calibrated.

Application of Differential pressure sensor

Differential pressure sensors are versatile and are widely used in various fields. It is mainly used for anemometers and air conditioning. In industrial equipment, the operating status of equipment such as pumps and compressors is monitored, and filter clogging monitoring is also used. It is also used to measure the volume of liquid in the tank. At this time, the structure of the differential pressure sensor can be used to measure the differential pressure of different phases (forms) such as the liquid in the tank and the atmospheric pressure.
