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.

Reduce process variability, increase yield, and improve product reproductibility with reference accuracy as low as 0.025% of span backed by an unconditional stability guarantee of 0.1% of URL for 10 years. Yokogawa pressure instruments offer uncompromising quality, durability, and longevity.


  • Accurate level readings are essential to the safe, reliable, profitable operation of your plant. Liquid Level transmitters measure differential pressure to infer the level in a vessel.

  • 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.

  • Diaphragm Seal System can be used to measure liquid, gas, or steam flow as well as liquid level, density, and pressure.

  • Gauge Pressure transmitters compare a pressure relative to atmospheric measure.

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

  • Draft Pressure transmitters are a unique type of differential transmitter that is designed to measure small differences in very low static pressure environments.

  • Using Bernoulli's equation, Differential Pressure transmitters can be used to infer the flow of fluid through a pipe.

  • There are several technologies on the market to measure mass flow. One is the Multi-variable Pressure Transmitter.

  • A Multi-Sensing transmitter combines transmitters for Differential Pressure, Gauge Pressure, and Temperature into one field instrument.

  • Hygienic Pressure Transmitters are designed to fulfil the requirements of hygienic and pharmaceutical application

Yokogawa has more than 45 years experience in the development, design, and manufacture of pressure sensors and pressure instruments. The DPharp series of digital pressure transmitters use a differential pressure high accuracy resonance (DPharp) sensor that represents one of the most revolutionary advances in transmitter technology.
