Lec 28 II Resistive and Inductive Pressure transducer

Описание к видео Lec 28 II Resistive and Inductive Pressure transducer

A resistive pressure transducer has strain gauges bonded to the surface of the non-media contacted side of the diaphragm so that any change in pressure will cause a momentary deformation of the elastic material resulting in a change of the resistance of the strain gauge that is converted into a useable electrical signal.

An inductive pressure transducer uses the principle of inductance to convert the flexing of a diaphragm into the linear movement of a ferromagnetic core. The movement of the core is used to vary the induced current generated by an AC powered primary coil on another secondary pick-up coil.
