Yokogawa has more than 45 years experience in the development, design, and manufacture of pressure sensors and pressure transmitters. 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.
Timeline of Yokogawa's 45 Years of Pressure Sensor Advances.
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 transmitters compare two pressures and transmit the difference to a control unit. Differential Pressure transmitter have a limitless number of industrial applications.
Diaphragm Seal System can be used to measure liquid, gas, or steam flow as well as liquid level, density, and pressure.
Draft Pressure transmitters are a unique type of differential transmitter that is designed to measure small differences in very low static pressure environments.
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.
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

Level transmitter configuration can be very time consuming. DPharp transmitters with advanced software functionality eliminate this time consuming task. With maintenance shops getting smaller, finding equipment that allows us to do more with less becomes a priority.
Considering safety and environmental issues such as combustion efficiency and decreasing NOX and CO in exhaust gas, it has become important to control O2 concentration in garbage incineration processes.
H2S management of exhaust gas in black liquor recovery boilers is required to meet an environmental regulations.
Differential pressure level measurement has an enemy- temperature. Temperature can have a negative effect on the accuracy of level measurement. This article covers why temperature has this effect and how it can be reduced.

The Yokogawa family of pressure transmitters features a unique digital pressure sensor called DPharp to provide the most stable and accurate pressure measurement offered today.
The unique design of the DPharp sensor allows for measuring differential pressure and static pressure at the same time.
Yokogawa's unique capsule design equalizes overpressure within the capsule before it can reach the measurement sensor.
Calibration frequency is determined by factoring the real-world performance of a device against the required measurement threshold. Yokogawa’s superior performance delivers increased performance in real-world conditions.
The response time of a transmitter is key to safe and accurate process control.
Yokogawa’s DPharp pressure transmitter family features the fastest response time available on the market today.
The rich display of DPharp transmitters makes installation, commissioning and operation easy.
The advanced diagnostics in Yokogawa EJX pressure transmitters provide powerful insight into your process to predict failures before they happen.
There are many types of pressure transmitter mounting configurations for new and replacement installations.
Using the DPharp universal mount flanges and universal mounting bracket, almost any installation can be achieved.
Yokogawa’s transmitters can be easily programmed to output and display volume of irregularly shaped tanks with its signal characterizer function.
By using open standards and enabling technologies, the multi-sensing and advanced diagnostic capabilities in DPharp intelligent devices can be effectively utilized.
Every Yokogawa pressure transmitter is designed from the ground up with safety in mind.
At the heart of this philosophy is the inherently safe DPharp sensor.
All Yokogawa pressure transmitters come with safety certification as standard and at no extra cost.
Multi-variable transmitters deliver improved mass flow accuracy and reduced total cost of ownership.
