Abstract
A transducer for providing an output signal having a value determined by an input pressure differential includes a capacitance manometer having a first input for receiving a first input pressure and a second input for receiving a second input pressure, the capacitance manometer having a capacitance determined by the difference between the first and second input pressures, and an output circuit connected to the capacitance manometer for providing an output signal having a value dependent upon the capacitance.
