A pressure sensor works by converting pressure into an analogue electrical signal. differential pressure measurement So, how does a differential pressure transmitter work? DPT series pressure transmitters represent the latest development in their class. Pressure drops across rooms or across a filter can alert service technicians for maintenance. The mechanical part of the sensor is used to produce the pressure differential, while the electrical part of the sensor measures the pressure difference. BME280 is a precision sensor, is soldered onto PCB. Differential Pressure Switch Working Principle A Differential Pressure Switch, just like a regular pressure switch, is a simple electro-mechanical device that operates on the basic principles of levers and opposite forces.
