Pressure Inductive Transducer

Pressure Inductive Transducer: Pressure Inductive Transducer – A simple, arrangement, wherein a change in the inductance of a sensing element is produced by a pressure change, is given in Fig. 13.22. Here the pressure acting on a movable magnetic core causes an increase in the coil inductance corresponding to the acting pressure. The change in

Differential Output Transducer

Differential Output Transducer: The Differential Output Transducer consists of a coil which is divided into two parts, as shown in Figs. 13.17(a) and (b). (Inductive transducers using self inductance as a variable use one coil, while those using mutual inductance as a variable use multiple coils.)  Normally the change in self inductance, ΔL, for inductive

What is an Inductive Transducer?

What is an Inductive Transducer?: Inductive Transducer may be either of the self generating or the passive type. The self generating type utilizes the basic electrical generator principle, i.e. a motion between a conductor and magnetic field induces a voltage in the conductor (generator action). This relative motion between the field and the conductor is

Thermistor Working Principle

Thermistor Working Principle: Thermistor Working Principle – The electrical resistance of most materials changes with temperature. By selecting materials that are very temperature sensitive, devices that are useful in temperature control circuits and for temperature measurements can be made. Thermistor (THERMally sensitive resISTOR) are non-metallic resistors (semiconductor material), made by sintering mixtures of metallic oxides

Resistance Thermometer Working Principle

Resistance Thermometer Working Principle: The resistance of a conductor changes when its temperature is changed. This property is utilized for the measurement of temperature. The Resistance Thermometer working principle is an instrument used to measure electrical resistance in terms of temperature, i.e. it uses the change in the electrical resistance of the conductor to determine
