What is Electromechanical Chopper?: Electromechanical Chopper - An ac amplifier must see ac in order to perform useful work. A fair number of chopping and modulation techniques are available to…
Chopper Type DC Amplifier: A simple ac amplifier Transformer may be used to amplify a dc input through the use of additional circuit component known as chopper. In this circuit,…
Integrator using Op Amp: An Integrator is a circuit that performs the mathematical operation of integraÂtion because it produces an output voltage that is proportional to the integral of the…
Measurements of Thickness using Beta Gauge: Beta Gauge - A common and characteristic feature of a radioactive element is that they disintegrate spontaneously to produce fresh radioactive elements called daughter…
Magnetic Flow Meters: Magnetic Flow Meters are the first type of flowmeters to be considered for high corrosive applications and for applications involving measurement of erosive slurries. These meters work…
Linear Variable Differential Transformer (LVDT): The differential transformer is a passive inductive transformer. It is also known as a Linear Variable Differential Transformer (LVDT). The basic construction is as shown…
Resistive Position Transducer: The principle of the Resistive Position Transducer is that the physical variable under measurement causes a resistance change in the sensing element. (A common requirement in industrial…
Kelvins Bridge and Kelvins Double Bridge: When the resistance to be measured is of the order of magnitude of bridge contact and lead resistance, a modified form of Wheatstone's bridge,…
