EJA110E Differential Pressure Transmitter
Category: EJA-E Series Transmitters
The EJA110E high-performance differential pressure transmitter employs single-crystal silicon resonant sensor technology and is suitable for measuring flow, liquid level, density, and pressure of liquids, gases, or steam. The EJA110E converts measurement differential pressure into a 4-20mA DC current signal output, enabling the measurement, display, or remote monitoring of static pressure. It features rapid response, remote setting, and self-diagnosis capabilities.

Specification Structure
Durable and robust construction
A robust and durable construction helps reduce malfunctions in your factory. Featuring a four-bolt pressure retention design, DPharp digital sensor, Teflon-lined 316L stainless steel flange gaskets, and ANSI/ISA 12.27.01 certified dual seal – all design features are aimed at extending the transmitter's lifespan.
Note: Refer to the general specifications of each model for NACE MR0175 / MR0103 standards.
Overvoltage Protection
The robust design of the DPharp sensor itself can withstand overpressure impacts, and additionally, the mechanical design inside the diaphragm box further provides overpressure protection, safeguarding the transmitter from damage due to overpressure events such as incorrect valve group operation and unexpected pressure surges.
Independent third-party certification
The performance and reliability of the EJX-A series transmitters have been certified by international independent third-party organizations TÜV Rheinland and EXIDA.
Functional safety
The EJX-A series transmitters are all designed in compliance with IEC61508:2010 (Parts 1-7) and IEC61511:2004 (Parts 1-3), and are certified. Each unit meets SIL2 safety requirements, and redundant usage meets SIL3 safety requirements. The EJX-A series transmitters can meet both production application and safety requirements with a single unit, without the need for redundant configuration.
DPharp Digital Sensor
The DPharp digital sensor continuously outputs frequency signals even when the process pressure remains unchanged. Therefore, if the sensor malfunctions, the transmitter can detect it promptly, preventing any confusion between sensor failure and an unchanged process pressure.
Back-Check Self-Inspection System
Patented Back-Check self-inspection system, which simultaneously transmits and converts signals from the transmitter, and performs real-time reverse calculations to confirm and detect the accuracy of the computations.
