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…
WHAT IS TRANSDUCER? For most instrumentation systems, the input quantity will be a non-electrical quantity. The non-electrical quantity is converted into an electrical form for using electrical methods and techniques for measurement, manipulation and control. The device which when actuated, transforms energy…
What is a smart transmitter? A microprocessor-based smart transmitter has a memory that can perform calculations, produce diagnostics and out-perform older, more conventional transmitters when it comes to accuracy and stability. A Smart Transmitter will also have a wireless communication protocol which…
In a conventional analog electronic process transmitter typically have only two calibration adjustments: one for zero and another for span, modern transmitter offers more components in need of adjustment. Smart transmitter: The aim of the analog-to-digital converter (ADC) is to transform the…
What is a transducer A transducer is a device that can convert one form of energy to other, transducers are classified into many types some of them are electrical, magnetic, and piezoelectric. What is a piezoelectric effect In a piezoelectric material, if…
