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.

Yokogawa have been manufacturing electronic pressure transmitters for more than four decades. We revolutionized the industry and set a new standard for pressure measurement with the introduction of the DPharp digital sensor in 1991. The superior performance of the new technology enabled exponential market expansion. Yokogawa continues, the digital evolution with the enhancement of our DPharp family to deliver best in class pressure measurement solutions to our esteemed customers.
