HOW DPT WORKS?

Answer Posted / eswar

the differential presser acting on a sensing diaphragm
produces a force therefore we get diaphragm
deformation(small 10^-5m).This displacements we can measure
through variable capacitance or variable reluctance
,resistive strain gauge sensors.This sensor output is
connected to a bridge which gives the output voltage.Then
instrumentation amplifier converts the voltage to current
which we can transmit to the control room.
