Oscillator Transducer

Published on 24/2/2012 & updated on Tuesday 8th of May 2018 at 11:52:05 AM
These types of transducers are mostly used as secondary transducers and their output is calibrated in terms of input quantity. It can be used to measure force, pressure, displacement etc. Oscillatory transducer consists of following parts Mechanical linkage: This is used to link the input quantity to the secondary transducer, i.e. oscillatory transducer, by actuating it. It may include gears or some other linkage system.

Oscillator: As we know oscillator are used to generate desired frequency. The oscillator used here consists of LC tank/circuit. The output frequency is generated according to the input source. Frequency Modulator: The output frequency from the oscillator may need some modification for telemetry purpose. This modulation is achieved by frequency modulator. After modulation the output frequency is suitable for telemetry purpose. Force Summing Member: This is used to change the capacitance or inductance of an LC oscillator circuit. It transfers the pressure to mechanical linkage.
