What is a proximity sensor and what is it used for A sensor is a device that can convert the physical parameters, like temperature, humidity, speed, etc into a signal which is then measured electrically. A proximity sensor is a sensor that…
What is a proximity switch and what is it used for? How do proximity switches work A proximity switch is used to determine how close an object is, or the proximity of an object. The proximity of an object is determined by…
What is a smart sensor and how is it different from a normal sensor A sensor is a device that would create an electrical signal which is related to the quantity that is measured by it. So this device would measure the…
What is pressure gauge? The pressure gauge is one of the widely used instrument to measure pressure. The widely used bourdon gauge measures and indicates pressure. The principle used in bourdon pressure gauge is that a flattened tube tends to straighten or retain its circular…
What is Pressure Switch? Pressure switch is a device that closes the electrical contact when a certain set fluid pressure has been reached in its input. It is designed to make contact either a rise in pressure or a fall in pressure….
What is Transmitter? Transmitters are instruments used to generate and send electromagnetic waves which includes message or signal. A transmitter produces radio waves with the help of Antenna. Transmitter itself combines a sensor and the sensor measures the process variable and generates…
