Differential pressure transducer (DPT) is meant for measuring differential pressure between two pressures P1 and P2, the pressure P1 and P2 are supplied independently through bellows, the forces developed due to these pressures act on a balanced beam sensing element. Four resistance foil strain gauges are bonded on this sensing element beam which deforms proportionately to the difference in the pressure between P1 and P2. The electrical output signal is positive when P1 is greater than P2.
