What is a Pressure Transmitter ? A pressure transmitter is a transducer that converts pressure into an electrical signal. It outputs both analog and digital signals corresponding to the pressure. A pressure transmitter measure three phenomena : Differential Pressure,Gauge Pressure,Absolute Pressure. The most common and useful industrial pressure measuring instrument is the differential pressure transmitter. This instrument …
Working Principle Of Bourdon Gauge If a tube having oval cross section is subjected to pressure its cross section tends to change from oval to circular. Construction of a Bordon Gauge Bourdon tube gauges consist of a circular tube. One end of the tube is fixed while the other end is free to undergo elastic deformation under …

Pressure is defined as force per unit area. Pressure above atmospheric is mostly measured in pounds per square inch (PSI), or in kilo gram per square centimeter (kg/cm2) gauge or absolute. For lower pressure (below about 10 psi), inches or cms. of water or mercury column are frequently used. For near atmospheric pressure, we refer …
