Using cutting-edge single-crystal silicon resonant sensor technology, the Yokogawa EJX118A Diaphragm Sealed Differential Pressure Transmitter works really well. This unique emitter does an excellent job of measuring flow, liquid level, density, and pressure even in difficult settings with high temperature, high vacuum, and high viscosity. Its strong build makes sure that the 4–20 mA DC current signal output is correct and that you can keep an eye on your important processes.

When industrial facilities measure pressure in tough settings, they face unique problems. When traditional receivers come into contact with toxic materials, very high or low temperatures, or substances that crystallize, they often stop working. This diaphragm-sealed approach takes these problems directly head-on.
You get consistent readings even when conditions are tough. The sealed design keeps your investment safe and keeps the accuracy over long periods of time. Consistent performance and fewer repair needs are good for your business.
Revolutionary DPharp Digital Sensor Technology
Its state-of-the-art DPharp digital sensor is what makes this emitter work. This technology differs from standard sensors because it constantly sends frequency signals when process pressure stays the same. This means you can find sensor problems right away, which saves money and keeps safety issues from happening.
Exceptional Overpressure Protection
With two-layer overpressure measures, your gear stays safe. The strong DPharp sensor design naturally fights changes in pressure. Additionally, the way the inside is mechanically designed adds extra safety against sudden pressure increases and mistakes in how the valve works.
Advanced Self-Diagnostic Capabilities
The patented Back-Check self-diagnostic system works continuously. It performs reverse calculations in real-time while transmitting signals. This ensures calculation accuracy and immediately detects any irregularities in system performance.

Built to Last
The four-bolt pressure retention system makes sure that it will work for a long time. The 316L stainless steel structure with Teflon coating avoids corrosion and wear. Double sealing that is ANSI/ISA 12.27.01 approved offers extra safety against the elements.
Safety-First Design
This transmitter meets very high safety standards, including IEC 61508:2010 and IEC 61511:2004. SIL2 safety standards are met by single units, but SIL3 approval can only be achieved by setups with extra parts. One device can be used for both work and safety purposes.
Third-Party Validated Performance
Independent certification from TÜV Rheinland and EXIDA validates the transmitter's performance and reliability. These certifications provide confidence in your equipment selection and help meet regulatory requirements.
