What is pressure gauge and how is pressure gauge calibrated?

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 …

HOW TO CALIBRATE DIFFERENTIAL PRESSURE TRANSMITTER?

What is a Differential Pressure Transmitter? The Differential pressure transmitter is commonly used in industries as pressure measuring instrument. It is a device that measures two opposing pressures in a pipe or a vessel. This equipment will sense the difference in pressure between two ports and produce an output signal with reference to a calibrated pressure range. In the Differential pressure transmitter, as …
