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 reproducibility 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 instruments compare two pressures and transmit the difference to a control unit. These transmitters have a limitless number of industrial applications.

  • Gauge pressure instruments 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 instruments 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.

  • Yokogawa offers a complete line of Manifolds, Communicators, Remote Indicators, and Pressure Calibrators to support your Pressure Transmitters. 

  • Differential Pressure Flow is one of the oldest forms of measurement. The Egyptians began using flow simple DP flow devices to predict spring floods. Roman aqueducts used simple obstructions in the water with marks on the wall to measure the water flow to their cities. Even the Sumerians used DP flow devices in the process of brewing beer.

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.

Overview:

The primary function of a utility boiler is to convert water into steam to be used by a steam turbine / generator in producing electricity. The boiler consists of a furnace, where air and fuel are combined and burned to produce combustion gases, and a feedwater tube system, the con- tents of which are heated by these gases. 

Application Note
Overview:

Hydrogen is the simplest and smallest atomic element. Water, acids, bases, and the immense family of organic compounds all contain hydrogen. Even though hydrogen is not corrosive, it can cause problems for pressure transmitters through Hydrogen Permeation.

Industries:
Overview:

DPharp performance in boiler drum level measurement applications is superior to metallic capacitance type pressure transmitters. Improved performance can be attributed to the unique resonant silicon sensor design with dual resonators.
