Yokogawa Remote Seal Dp Transmitter

Part of the renowned DPharp EJA-E series, the EJA118E utilizes advanced differential pressure sensing technology combined with remote diaphragm seals. This configuration is essential for applications where the process medium cannot come into direct contact with the transmitter's sensor due to extreme temperatures, corrosiveness, or the risk of clogging. By isolating the sensing element, the EJA118E ensures consistent performance and longevity, even in the harshest industrial environments, while delivering the high accuracy and fast response times expected from Yokogawa instrumentation.

Key Features and Technical Specifications

High Accuracy & Stability: Delivers a reference accuracy of ±0.2% of span and maintains stability under varying static pressures and temperatures.
Fast Response: Achieves a 200-millisecond response time, enabling timely reaction to process fluctuations.
Advanced Diagnostics: Features DPharp digital sensor technology that provides predictive diagnostics, such as impulse line blocking detection, to prevent unscheduled downtime.
Safety Certified: Comes standard with IEC 61508 certification for SIL 2 (single) and SIL 3 (dual) safety applications.
Versatile Connections: Offers a wide range of flange sizes, ratings (JIS, ANSI, DIN), and extension lengths to fit diverse installation requirements.

Industrial Applications and Smart Design

The EJA118E is widely used in industries like Oil & Gas, Chemical Processing, and Power Generation. It is particularly effective for measuring the level, density, and flow of fluids that are highly viscous, precipitate solids, or solidify at ambient temperatures. The yokogawa remote seal dp transmitter excels in these scenarios by eliminating the need for wet legs and complex heat tracing. With its rugged construction and intelligent multi-sensing capabilities-simultaneously measuring differential and static pressure-the EJA118E provides a comprehensive solution for improving plant safety and operational efficiency.
