Specs and structure
Durable and robust construction
A robust and durable construction helps reduce breakdowns in your factory. Four-bolt pressure retention design, DPharp digital sensor, Teflon-coated 316L stainless steel flange gasket, ANSI/ISA 12.27.01 certified double seal – all design features extend the transmitter's lifespan.
Note: Refer to the general specifications of each model for NACE MR0175 / MR0103 standards.
Overvoltage Protection
Not only does the DPharp sensor's robust design itself withstand overpressure effects, but the mechanical design inside the diaphragm box also further provides overpressure protection, ensuring the transmitter is immune to, and even damage from, overpressure events such as incorrect valve group operation and unexpected pressure surges.
Independent third-party certification
The EJX-A series transmitters have been certified for their performance and reliability by the international independent third-party organizations TÜV Rheinland and EXIDA.
Functional Safety
The EJX-A series transmitters are designed and certified in accordance with IEC61508:2010 (Parts 1-7) and IEC61511:2004 (Parts 1-3), meeting SIL2 safety requirements individually and SIL3 with redundancy. Using a single EJX-A series transmitter can meet both production and safety requirements 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 quickly detect it, preventing the misinterpretation of sensor failure as an unchanged process pressure.
Back-Check Self-Inspection System
Patented Back-Check self-inspection system, which performs real-time reverse calculations while the transmitter transmits and converts signals, to confirm and detect the accuracy of the calculations.
