A capacitive transducer is a passive transducer that works on the principle of variable capacitances. It is used to measure physical quantities such as displacement, pressure, etc. Construction of capacitive transducer A capacitive transducer contains two conducting parallel metal plates separated by a dielectric medium. Working Principle of capacitive transducer The capacitance between these two …

An inductive transducer works on the basic principle of change in inductance due to any change in the measurand. A change in measurand changes the flux and this change in flux changes the inductance. This change in inductance can be calibrated in terms of measurand. Inductive transducers works on one of the following principles Change …

A Strain gauge(resistance strain gauge) is an important type of resistance transducer whose resistance varies with applied force. It can be used to convert force, pressure, tension into a change in electrical resistance. The applied strain can be measured by this change in resistance. Basic Principle We know that the resistance of a conductor is …
