Pressure Detection Circuitry:

Any of the pressure detectors previously described could be joined to an electrical device to form a pressure transducer. A Transducers could generate a change in inductance, capacitance, or resistance.

EXPLAIN how a strain gauge pressure transducer generates an output signal involving:

a.         Method of detection

b.         Method of signal generation

Given a basic block diagram of a classical pressure detection device and STATE the aim of the following blocks:

a.         Sensing element

b.         Transducer

c.         Pressure detection circuitry

d.         Pressure indication
