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…
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…
Thermocouple Connection: One of the most commonly used methods of measurement of moderately high temperature is the thermocouple effect. When a pair of wires made up of different metals is…
Platinum Resistance Thermometer: Platinum Resistance Thermometer - The resistance of a conductor changes when its temperature is changed. This property is used for measurement of temperature. The Resistance Thermometer uses…
Resistance Temperature Detector (RTD): Resistance Temperature Detector (RTD) commonly use platinum, nickel or any resistance wire whose resistance varies with temperature and which has a high intrinsic accuracy. They are…
Working Principle of Piezoelectric Transducer: A symmetrical crystalline materials such as Quartz, Rochelle salt and Barium titanate produce an emf when they are placed under stress. This property is used…
Capacitive Pressure Transducer Working Principle: Capacitive Pressure Transducer Working Principle - A linear change in capacitance with changes in the physical position of the moving element may be used to…
