Chapter 4 Transducers and Control System Components
A transducer is a device that transforms one form of energy into another.
Transducers are generally made as small as possible, and the energy being transferred is small.
Conversion between input and output is done quantitatively using a calibration process.
Transducers use basic physical laws to measure physical parameters using a sensing element that is the heart of the transducer.
The parameters measured in a servo control systems are position and motion while the parameters measured in process control systems are temperature, flow, level, pressure, pH, viscosity, color, salinity, and others.
