Yokogawa EJA118E Diaphragm Sealed Differential Pressure Transmitter

Yokogawa EJA118E Diaphragm Sealed Differential Pressure Transmitter

For your most difficult manufacturing needs, the Yokogawa EJA118E Diaphragm Sealed Differential Pressure Transmitter gives you the most accurate measurements. This emitter is great at handling tough conditions where the media have high temperature, high pressure, high viscosity, and are prone to crystallization. It was made with an advanced single-crystal silicon resonant sensor technology. You will benefit from its proven ability to measure flow, liquid level, density, and pressure while turning differential pressure into reliable 4–20 mA DC current signs that work perfectly with your control systems.

Why Choose This Differential Pressure Transmitter?

This transmitter gives you the reliability your work needs when you need exact readings in tough situations. The strong build has a four-bolt pressure retention system that greatly extends the service life. This device measures both the main variable and the secondary variable. This makes it ideal for keeping an eye on static pressure and difference pressure at the same time.

Unlike standard receivers, this unit uses DPharp digital sensor technology. Unlike standard monitors, this one keeps sending frequency messages even when the pressure in the system doesn't change. This means you won't mistake sensor problems for stable process conditions and will instead find them right away.

Key Technical Advantages

Your facility benefits from several breakthrough technologies integrated into this transmitter:

Overpressure Protection: The mechanical design inside the diaphragm provides dual-layer protection. Even during incorrect valve operations or unexpected pressure surges, your transmitter remains protected and operational.

Back-Check Self-Diagnosis: This patented system performs real-time reverse calculations while transmitting signals. You get instant confirmation of calculation accuracy and immediate detection of any processing errors.

Fast Response Times: With main variable response in just 200 milliseconds and auxiliary variable response in 500 milliseconds, you capture rapid process changes without delay.

Superior Range Flexibility: The 40:1 range ratio for M-type diaphragms and 20:1 for H-type diaphragms gives you exceptional measurement flexibility across different operating conditions.

Technical Specifications

Safety and Compliance Features

This Yokogawa EJA118E Diaphragm Sealed Differential Pressure Transmitter meets the highest safety standards for critical applications. It's designed according to IEC 61508:2010 and IEC 61511:2004 standards. A single unit satisfies SIL2 safety requirements, while redundant configurations meet SIL3 requirements. This means you can use one transmitter for both production and safety applications, eliminating costly redundant configurations.

The robust construction includes ANSI/ISA 12.27.01 certified double sealing and Teflon-coated 316L stainless steel flange gaskets. These features ensure long-term reliability in corrosive environments and high-pressure applications.

Performance You Can Trust

Independent third-party certifications from TÜV Rheinland and EXIDA validate the performance and reliability claims. The EJX-A series maintains ±3σ specification consistency, ensuring predictable performance across multiple units.

The four-bolt pressure retention design reduces maintenance requirements and extends operational life. Your facility experiences fewer malfunctions and lower total cost of ownership compared to conventional transmitters.

Remote Monitoring Capabilities

You gain comprehensive remote monitoring and configuration capabilities. The transmitter supports remote setting adjustments and provides detailed diagnostic information. This reduces the need for field visits and enables proactive maintenance scheduling.

The digital communication protocols allow seamless integration with modern control systems. You can monitor both differential and static pressure simultaneously, providing complete process insight from a single device.
