A barometer is a pressure sensor that is used to measure atmospheric pressure. This device is very sensitive, and they are capable to measure the absolute pressure. A barometer can measure the pressure exerted by the atmosphere with the help of water, air, or mercury. The atmospheric pressure would change according to the distance above …
A piezoelectric sensor can be used to measure the displacement, pressure, temperature, force, and strain. These sensors operate according to the piezoelectric effect, the piezoelectric effect is the formation of electric potential in a crystal if it is subjected to mechanical pressure. The crystals that are mostly used will be quartz, and barium titanate. The …
A manometer is an instrument which is widely used for many industrial applications, this device can be used to measure the pressure difference between two points in a pipe or it can also be used to determine the pressure difference between two pipes. The manometer can measure the pressure by using the relation between 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 form in cross-section when pressure is applied.To measure pressure which is lower than …

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. Most pressure switch use diaphragm or bellow as a sensing element. The deflection …

HIPPS: HIPPS is part of the Safety Instrumented System (SIS) to avoid overpressure by shutting off the source and collecting the pressure on the system’s upstream side. Instruments provide the security function in HIPPS. The Safety Loop is made up of one or more initiators, final elements, and a logic solution. HIPPS provides protection against overpressure …
The principle of differential pressure transmitter (DPT) level measurement is based on hydrostatic head. They are used in vessels that are open and enclosed. Usually, differential transmitters are connected to the side of a vessel or tank with insulation equipment. Installation of DPT: The capillary seal filled is susceptible to variations in ambient temperature. Protection …

What is Creep? Creep is a process of degradation observed in steels and other materials used for pressure equipment. Creep is one of the most complicated processes of degradation observed in pressure equipment. The pressure vessel will expand when a pressure vessel is subjected to internal pressure and is made of a material that displays …

What is Diaphragm seal? Diaphragm seals, also known as chemical seals, are used to measure pressure when the process medium should not come into contact with the measuring instrument’s pressurized components. A diaphragm seal has two primary tasks: Separation of the measuring instrument from the process medium Transfer of the pressure to the measuring instrument …

There are two basic categories of diaphragm elements: rigid metal diaphragms and slack diaphragms linked to driving plates. Schaffer gauge The simplest form of diaphragm gauge is the Schaffer gauge, shown in above figure. It consists of a corrugated diaphragm of about 65 mm in diameter heat treated stainless steel and held between two flanges. …
