Signal Conditioning in Instrumentation Articles: 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…
Partial Discharge Measurements: Earlier the testing of insulators and other equipment was based on the insulation resistance measurements, dissipation factor measurements and breakdown tests. It was observed that the dissipation…
Symmetrical Optimum: Symmetrical Optimum - Sometimes automatic control systems contain integrating also besides first order delay elements, proportional elements and deadzones. Such a system when compensated on the basis of magnitude…
Closed Loop Control of DC Motor: Closed Loop Control of DC Motor - The dynamic behaviour of a system is described by a set of differential equations. On many occasions…
Static Relay: The term 'static relay' is generally referred to a relay incorporating solid state components like transistors, diodes, resistors, capacitors, etc. In this type of relay, the functions of…
Direct Digital Control: Developments in digital electronics have led to many industrial processes being computer controlled. The first system used was Direct Digital Control (DDC), in which a computer measured…
Delta Modulation(DM): Delta modulation(DM) is process of modulation in which train of fixed width pulses is transmitted. Their polarity indicates whether the demodulator output should rise or fall at each…
Sensors Based Computer Data Systems: This Sensors Based Computer Data Systems describes hardware/software which is commercially available at several levels of completeness, ranging from single board computer "front ends" to…
