Pressure Transmitter

Pressure Transmitter

pressure transmitter , often called a pressure transducer, is a transducer that converts pressure into an analog electrical signal. Although there are various types of pressure transmitters The conversion of pressure into an electrical signal is achieved by the physical deformation of strain gages which are bonded into the diaphragm of the pressure transmitter and wired into a wheatstone bridge configuration. Pressure applied to the pressure transmitter produces a deflection of the diaphragm which introduces strain to the gages. The strain will produce an electrical resistance change proportional to the pressure.

The Electrical Output of pressure transmitter Pressure transmitters are generally available with three types of electrical output; millivolt, amplified voltage and 4-20 mA . Below is a summary of the outputs and when they are best used.
