Pressure Transmitters

Definition - What does Pressure Transmitters mean?

Pressure Transmitters are devices that are used to measure the pressure of liquids and gases. The transmitters usually work as transducers which generate electrical signals as functions of the pressure imposed. They are used for monitoring and controlling thousands of activities and can also be used to measure other variables indirectly like the water level, altitude, gas or fluid flow and speed. They can drastically be distinct in design, performance, technology, application suitability and cost. They are designed to measure and capture high speed pressure changes in a dynamic mode.

Petropedia explains Pressure Transmitters

Pressure Transmitters are used to convert pressure into electrical signal. This conversion can be achieved by physical deformity of the strain gages that are bonded to the diaphragm and are wired into the configuration of the wheatstone bridge. A deflection of diaphragm is produced by the pressure applied to the pressure transducers. This applied pressure introduces a strain on the gages. The strain out-turns a change in electrical resistance that is commensurate to pressure. These electronic pressure measurement instruments have low material strain and excellent dynamic characteristics that result in the high resistance to the long-term durability and alternating loads.
