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

A potentiometer is a device where a resistive wire is wound on an insulating core provided with a sliding contact. It can be excited with a DC or AC voltage source. The slider movement can be translational (straight) rotational or a combination of both. Schematic diagram of a resistive potentiometer is shown in figure. Here,

Resistance transducer is one of the simplest and important groups of transducers. These are transducers whose electrical resistance is varied in accordance with the input quantity (measurand). Quantities like displacement, acceleration, force, pressure, temperature etc. can be transduced using this type of transducers. Basic Principle of Resistance Transducer The basic principle of a resistance transducer

The basic requirements of a sensor are Accuracy: It is the level of exactness between the measured value and the true value. Hysteresis: It is the difference in the output of the sensor for a given input x when x reaches this value in upscale direction and downscale direction. Linearity: It is specified in terms
