Read MoreA transducer is a device that converts one form of energy into another. It is widely used in electrical measurements to convert physical parameters such as temperature, pressure, and displacement into electrical signals for further processing.
Example: A thermocouple converts temperature into a voltage signal.
Transducers are classified into:
Resistive transducers work by changing resistance with a change in physical parameters such as displacement or pressure. Examples include potentiometers and strain gauges.
Formula:
R = ρ (L / A)
where R is resistance, ρ is resistivity, L is length, and A is the cross-sectional area.
Capacitive transducers measure changes in capacitance due to variations in displacement, pressure, or dielectric material.
Formula:
C = ε₀ εr (A / d)
where C is capacitance, ε₀ is permittivity of free space, εr is relative permittivity, A is area, and d is the distance between plates.
Inductive transducers operate by varying inductance in response to changes in displacement or other physical parameters.
Formula:
V = -L (dI / dt)
where V is the induced voltage, L is inductance, and dI/dt is the rate of change of current.
