Pressure Transmitter


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.

Gauge Pressure

Gauge Pressure transmitters compare a pressure relative to atmospheric measure.

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.

Wireless Differential Pressure/Pressure Transmitters

Yokogawa offers a complete line of ISA100 compliant pressure transmitters. The line includes transmitters that can measure differential pressure, absolute pressure, and gauge pressure with a variety of different process connections.

Liquid Level

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.

Mass Flow (Multivariable)

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

Multi-Sensing

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

Diaphragm Seal System

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

Draft Pressure

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

Low Flow

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

Hygienic Pressure Transmitters

Hygienic Pressure Transmitters are designed to fulfill the requirements of hygienic and pharmaceutical application.
