Capacitive Transducers

Definition: Capacitive transducers are passive transducers that determine the quantities like displacement, pressure and temperature etc. by measuring the variation in the capacitance of a capacitor. As we know that a transducer changes a form of energy into another form. So, in the capacitive transducer, the change in the capacitance is used to measure the …

Difference Between LVDT and RVDT

Both LVDT and RVDT are basically sensors that are used to measure displacement. But the major difference between LVDT and RVDT is that an LVDT senses and transforms linear displacement into an electrical signal. While an RVDT senses angular displacement and transforms it into an electrical signal. Some more crucial differences exist between LVDT and …

Magneto Resistors

Definition: Magneto resistors are those components that exhibit the property of magnetoresistance. Basically, magnetoresistance is the phenomenon of change in resistance of a material when a magnetic field is applied. The current that flows through a magneto resistor, varies with the variation in the applied magnetic field. The resistivity of magnetoresistor depends on the mobility …

Signal Generator

Definition: A signal generator is an equipment that is used to produce signals of varying amplitude and frequency. It is usually a source for generating sinusoidal signals. However, it can also produce a signal in the form of a square wave, triangular wave or sawtooth wave etc. The adjustable frequency range of the generated signal …

Difference Between RTD and Thermistor

Both RTD and Thermistor are used to detect the change in temperature. However, the crucial difference between RTD and Thermistor lies in the material of their construction. RTD is constructed with materials that are pure metals whereas thermistors are fabricated with semiconductor materials of ceramic or polymers. Also the two shows variation according to the …

Transducers

Definition: Transducers are the device that is used for the conversion of energy from one form to another different but equivalent form. In terms of instrumentation, more specifically we can say, transducers are the devices that change non-electrical quantity into its electrical equivalent form. The converted form of energy by any transducer can also be …
