What is a Temperature Transducer?: Temperature Transducer is one of the most widely measured and controlled variable in industry, as a lot of products during manufacturing requires controlled temperature at…
Potentiometric Recorder Working Principle (Multipoint): Potentiometric Recorder Working Principle - The thermocouple or millivolt signal is amplified by a non-inverting MOSFET, chopper stabilized, feedback amplifier. This configuration has a very…
XY Recorder Working: XY Recorder Working - In most research fields, it is often convenient to plot the instantaneous relationship between two variables [Y = f(x)], rather than to plot…
Galvanometer Type Recorder: The D'Arsonval movement used in moving coil indicating instruments can also provide the movement in a Galvanometer Type Recorder. The D'Arsonval movement consists of a moving coil…
Wheatstone Bridge Diagram: A Wheatstone Bridge diagram in its simplest form consists of a network of four resistance arms forming a closed circuit, with a dc source of current applied…
Megger Circuit Diagram: Another common method of measuring resistances above 50 M Ω is the Megger Circuit Diagram (megaohmmeter) shown in Fig. 10.23(a). This instrument is used to measure very…
Beat Frequency Oscillator (BFO) | Block Diagram | Working and Limitations: In this Beat Frequency Oscillator, the outputs of two RF oscillators are applied to a square law detector and…
Working Principle of Digital Multimeter: Analog meters require no power supply, they give a better visual indication of changes and suffer less from electric noise and isolation problems. These meters…
