Signal Conditioning System: Signal Conditioning System - The measurand, which is basically a physical quantity, is detected by the first stage of the instrumentation or measurement system. The first stage…
Optical Pyrometer Working Principle: Optical Pyrometer Working Principle - Any metallic surface when heated emits radiation of different wavelengths which are not visible at low temperature but at about 550…
Pyrometer Working Principle: When temperature being measured is very high and physical contact with the medium to be measured is impossible or impractical, optical pyrometer based on the principle of…
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…
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…
Frequency Modulation Recording: When a more accurate response to dc voltages is required, an Frequency Modulation Recording system is generally used. In this FM system, the input signal is used…
Definition of Recorder: Definition of Recorder - A recorder is a measuring instrument that displays a time-varying signal in a form easy to examine, even after the original signal has ceased…
Wien Bridge Circuit Diagram: The Wien Bridge Circuit Diagram shown in Fig. 11.27 has a series RC combination in one arm and a parallel combination in the adjoining arm. Wien's…
