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…
Photoelectric Transducer Working Principle: Photoelectric Transducer can be categorized as photo emissive, photo-conductive or photo-voltaic. In photo emissive devices, radiation falling on a cathode causes electrons to be emitted from…
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…
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…
Automatic Bridge Circuit: The bridges discussed so far require that the controls be adjusted for balance after each capacitor (or other devices being tested) is connected to the bridge. In…
Automation in Digital Instruments: Automation in Digital Instruments - One of the advantages of digital multimeters is their ease of operation. The reading is easy to take and does not…
Digital Display System: Digital Display System - The rapid growth of electronic handling of numerical data has bought with it a great demand for simple systems to display the data…
What is Series Compensation in Power System?: Series Compensation - A capacitor in series with a line gives control over the effective reactance between line ends. This effective reactance is…
