When you need accurate differential pressure measurement in your industrial operations, the Yokogawa EJX120A High-performance Differential Pressure Transmitter delivers exceptional results. This high-tech micro-differential pressure emitter makes use of a very new resonant sensor built from single-crystal silicon. You can trust it to measure the flow, level, density, and pressure of gases, liquids, or clouds very accurately. The EJX120A changes the difference pressure it measures into a 4–20 mA DC current signal output. Its ability to quickly respond and set up remotely makes it a perfect fit for challenging industrial uses.

Superior Construction for Long-Term Performance
You will like the strong design that keeps your facility from having to shut down for long periods of time. The four-bolt pressure holding device makes sure that it works. The DPharp digital sensor technology allows for constant surveillance. Flange gaskets made of 316L stainless steel and Teflon coating are great at resisting chemicals. These features work together to greatly prolong the lifetime of your radio.
Unmatched Overpressure Protection
Your processes stay safe even when unexpected pressure events happen. The DPharp sensor is naturally resistant to overpressure collisions because it is well-built. The way that mechanics are designed inside adds more layers of safety. This kind of dual security stops pressure surges and wrong valve actions from causing damage. When you know your tools is safe, you can work with trust.
Advanced Safety Features
This differential pressure transmitter meets the highest safety standards. It complies with IEC 61508:2010 and IEC 61511:2004 requirements. A single unit satisfies SIL2 safety requirements. Redundant configurations achieve SIL3 compliance. You eliminate the need for additional redundant equipment while maintaining safety compliance.
