Differential Pressure Sensors

The pressure sensor is used to measure the pressure difference between two points. The difference between differential pressure sensors and general pressure sensors is that they have two pressure interfaces. Differential pressure sensors are generally divided into positive pressure end and negative pressure. In general, the pressure of the positive pressure end of the differential pressure sensor should be greater than the pressure of the negative pressure section to measure.

The differential pressure transducer or differential pressure transmitter are all differential pressure sensors. It is called differently while means the same in most situations depending on the countries and companies as differential pressure transducers are mostly used in the USA.  In Micro Sensor, we call the sensitive element a differential pressure sensor that usually outputs a millivolt signal. The differential transducers and differential pressure transmitters usually output digital signals like 4mA DC-20mA DC, Modbus, HART, etc.

The differential pressure sensors are often used for differential pressure monitoring and control of water, oil, and gases. It can also be used as a level sensor to measure the height of the liquid. Micro Sensor's differential pressure sensors are suitable for differential pressure measurement of oil tanks, water tanks as well as pipelines in industries like petroleum fields, chemical plants, etc.
