Pressure Transmitters

Pressure transmitters are used to measure the pressure or level of industrial liquids and gases. The output is transmitted to a control system. Accurate and stable process measurements ensure the safe, reliable, and profitable operation of your plant.

Compact, lightweight, intuitive and intelligent, Yokogawa pressure instruments simplify all aspects of handling, commissioning, installation, operation, and maintenance while delivering outstanding performance. Whether installed in the harsh environment of an offshore platform or a refinery in the burning desert heat, our DPharp series delivers accurate, repeatable, and high integrity process measurements.

Differential Pressure

Differential Pressure (DP) is defined as the difference between two pressures. Differential Pressure Transmitters use a reference point called the low-side pressure and compare it to the high-side pressure. Ports in the instrument are marked high-side and low-side.

Absolute Pressure

Absolute Pressure transmitters compare a pressure relative to Absolute pressure. Absolute pressure is always a positive value.
