Pressure Transmitters And Pressure Differential Transmitters

A pressure transmitter is a mechanical device that measures the expansion force of a liquid or gaseous sample and produces the measurement results as standard signals.

This type of sensor, also known as a pressure transducer, usually consists of a pressure-sensitive surface made of steel, silicon or other materials, depending on the composition of the analyte. Behind these surfaces, there are electronic components that are able to convert the force applied to the sample on the pressure sensor to an electrical signal.

Differential pressure transmitters (DPs) measure the difference between two pressures. They use a reference point called low pressure and compare it to high side pressure. The ports on the instrument are shown up and down. The DP reading rate can be negative or positive depending on the lower or higher value. If the bottom is open to the atmosphere, a DP transmitter can be used as a barometer transmitter. Examples of industrial applications: closed tank surface, density, filter health and DP flow (secondary element)
