DPT-4003 Differential Pressure Transducer
The DPT-4003 differential pressure transducer sensor operates on the capacitance principal and is capable of sensing ultra low differential pressures. In the capacitance cell, a very lightweight, responsive diaphragm deflects a small amount when pressure is applied. This deflection results in a change in capacitance, which is then detected and processed electronically into a 0-5 or 0-10 VDC output signal linear to the differential pressure.
