Working Principle

So imagine we have a process with -20 bar to 20 bar and no pressure in either chamber. At that point, the signal will read 12 milliamps (mA), representing 0 bar, 50 percent of the range. If we apply pressure on the high-pressure side of the differential pressure transmitter, then the value will rise towards 20 mA, giving you a positive reading. On the other hand, if we apply pressure to the low-pressure side, then that drives the signal towards 4 mA and negative reading.

We can find several options for converting the pressure in the sensing cell to an electronic signal - piezoresistive (strain gauge), piezoelectric, resonant, and capacitive methods all will get us there.

Differential pressure transmitters can measure the pressure difference in a sampling chamber divided by a diaphragm. The sensitive transmitter will register the shape of the diaphragm and record changes due to the pressure difference on both sides of the sampling chamber.
