When you need to measure pressure accurately in tough industrial settings, the Yokogawa EJX310A high-performance absolute pressure transmitter is very helpful because it is both accurate and tough. Using single crystal silicon resonant sensing technology, this high-tech emitter gives very exact readings for purposes involving liquids, gases, and steam. With its 4–20 mA DC current output and quick reaction time, it has the performance needed for very important process control uses in a range of industries.

Your building needs tools that works well even when things get tough. This emitter is made to work well in petroleum, petrochemical, chemical, power generation, and other industry settings. It uses the latest technology and is built to last.
The device has Yokogawa's new DPharp digital sensor technology, which gives a constant frequency sound. This means you can watch things in real time and find problems right away. This method tells you right away if there is a problem with a sensor, unlike old sensors that might hide failures as pressure changes.

Robust Construction for Extended Service Life
Your equipment investment needs to last. The four-bolt pressure retention design and 316L stainless steel construction with Teflon coating ensure long-term reliability. This ANSI/ISA 12.27.01 certified double sealing system minimizes maintenance requirements and extends operational life.
Superior Overpressure Protection
Things go wrong in the process. When they do, the Yokogawa EJX310A high-performance absolute pressure transmitter saves itself with two different safety systems. The DPharp sensor's form naturally resists overpressure impacts, and internal mechanical features offer extra safety against valve operation mistakes and sudden pressure increases.
Built-in Self-Diagnostics
The patented Back-Check system continuously validates signal processing accuracy through real-time reverse calculations. This self-monitoring capability helps you maintain process integrity and reduces the risk of undetected measurement errors.
The parts in your safety systems need to be approved. This transmitter is up to IEC 61508:2010 and IEC 61511:2004 standards for practical safety uses. SIL2 standards are met by a single unit, but SIL3 approval can only be achieved by setups with extra units. This gets rid of the need for different safety and output transmitters, which makes your system design easier to plan.
Independent groups TÜV Rheinland and EXIDA have confirmed this transmitter's performance and reliability, so you can be sure of your important measures.
The DPharp digital sensor continuously generates frequency signals, even during stable pressure conditions. This constant signal output enables immediate fault detection, distinguishing between actual process changes and sensor malfunctions. You get faster response to real process events and improved system reliability.
Remote setting capabilities allow you to configure and adjust the transmitter without physical access, reducing maintenance time and improving operational efficiency. The rapid response time of 90 milliseconds ensures you capture fast-changing process conditions accurately.
