The circuit of a single-coil inductance type is shown below. This type is used mainly in counting the no.of objects. This results in a change of the inductance in the circuit. When the armature of the circuit is moved, the air gap between the magnetic materials and the permeability of the flux produced in the circuit changes. Using LVDT, displacement is measured in terms of the voltage induced in the winding by moving the core in one direction. Linear Variable Differential Transducer (LVDT) is an example of an inductive transducer. These physical quantities are noted as measurands. A self-inductance or mutual inductance is varied to measure required physical quantities like displacement (rotary or linear), force, pressure, velocity, torque, acceleration, etc. What is an Inductive Transducer?ĭefinition: A transducer that works on the principle of electromagnetic induction or transduction mechanism is called an inductive transducer. This article describes an inductive transducer, which is an electrical transducer. A mechanical transducer can convert electrical energy into mechanical energy. An electrical transducer can convert physical energy into electrical energy. A transducer can be electrical or mechanical. An electric motor, solar cell, incandescent bulb, microphone, etc are examples of transducers. These are mainly used for automation, measurement, and control systems because the electrical signal needs to be converted to physical quantities like force, torque, motion, etc. That means a transducer has the ability to convert a signal of one form to another form.

A device that can convert one form of energy into another form is called a transducer.
