Sensor OR Actuator detects & measures the signals. Classification of signals with examples into six categories based on energies generated & received, Detect & Measured by Sensor OR Actuator. 1) Mechanical 2) Thermal 3) Electrical 4) Magnetic 5) Radiant 6) Chemical The explanation is based on INSTRUMENTATION ENGINEERING
As properties of the transducer biology, Transducers are the machine which is to be used as energy converter to converts one energy form to another energy form.Another way, the device by which non-electrical input quantity to be converted into electrical quantity is called Electrical Transducer.
Instrumentation Engineering which deals with the artistic & scientific measurement of Mechanical, Electrical & Electronic parameters. It is also controlled and measures the process variables within a production or manufacturing area.As well as measurement of the process variables used in industries is Level, Pressure, Temperature,
