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 …

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 …

Definition and Need for Calibration According to Webster’s Dictionary, calibrate means “to check, adjust, or standardize systematically the graduations of a quantitative measuring instrument.” As noted in Inter-Range Instrumentation Group (IRIG) 118-98 Volume I, “a telemetry system measurement begins with the sensing of a measurand by a transducer located either on a test vehicle or …
INTRODUCTION There are smart and conventional instruments and the calibration procedure of these types of instruments are entirely different in this session we are going to discuss about the difference between calibration of a HART &conventional instrument CALIBRATING A CONVENTIONAL INSTRUMENT For a conventional 4-20 mA instrument, a multiple point test that stimulates the input and …
