How to identify location of Fire Detectors
Fire detectors are designed to respond at an early stage to one more of the four major characteristics of combustion,
Basics of Venturi Flow Meter
By measuring change in pressure, the flow rate can be determined, as in various flow measurement devices such as venturi flow meter, orifice plates.
Coriolis Mass Flow Sensor Theory
The coriolis sensor will detect this time difference and convert it into a standard Measurement of flow signal in the process.
Factors Affecting the Performance of Ultrasonic Flow Meters
Ultrasonic Flow meter operates on principle of transit time differences. An acoustic signal is transmitted from one sensor to another to measure flow.
What is Field Transmitter Damping ?
The vast majority of modern field transmitters (both analog and digital) come equipped with a feature known as damping. This feature
How Process Control Loop Works
A typical process control system is shown in Figure. Assume the physical variable to be controlled is the temperature. Basically Industrial
Transistor Stabilisation
The collector current in a transistor changes rapidly when (i) the temperature changes, (ii) the transistor is replaced by another
Transistor Collector Characteristic Curves
Using a circuit like that shown in Figure (a), a set of collector characteristic curves can be generated that show how
Shockley Diode Working Principle
Named after its inventor, a Shockley diode is a PNPN device having two terminals as shown in Fig. (i). This device
