Product description
EJA-A pressure transmitter
EJA430E/High performance pressure transmitter adopts monocrystalline silicon resonant sensor technology, suitable for measuring the pressure of liquids, gases or vapors. The EJA430E converts measured pressure into a 4-20mA DC current signal output, with functions such as fast response, remote monitoring, and self diagnosis.
EJA-A pressure transmitterThe functional features include:
Accuracy ± 0.055% (optional accuracy ± 0.04%)
Stability ± 0.1% URL/10 years
Response time of 90 milliseconds
TUV and Exida SIL2/SIL3 certification
Local parameter settings (LPS)
Provide communication protocols such as HART 5/7, HART (1-5V DC) low-power type, FF fieldbus, PROFIBUS PA, and BRAN.

EJA430E membrane box
Durable and sturdy construction
Durable and sturdy construction can help reduce malfunctions in your factory. Four bolt pressure holding design, DPharp digital sensor, PTFE coated 316L stainless steel flange gasket, ANSI/ISA 12.27.01 certified dual seal - all design features aim to extend the lifespan of the transmitter.
Attention: Please refer to the general specifications of each model for NACE MR0175/MR0103 standards.
Overvoltage protection
Not only does the sturdy design of the DPharp sensor itself resist the effects of overpressure, but the mechanical design inside the membrane box further provides overpressure protection, protecting the transmitter from overpressure events such as incorrect valve group operation and unexpected pressure surges, and even damage.
Independent third-party certification
The performance and reliability of the EJA-E series transmitters have been certified by international independent third-party organizations T Ü V Rheinland and EXIDA.
Functional Safety
The EJA-E series transmitters are designed in accordance with the IEC61508:2010 (Parts 1-7) and IEC61511:2004 (Parts 1-3) standards and have obtained certification. Each unit meets SIL2 safety requirements, and redundant use meets SIL3 safety requirements. By using the EJA/EJX series transmitters, one can meet production applications 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. So if the sensor malfunctions, the transmitter can detect it immediately without mistaking the sensor malfunction for unchanged process pressure.
Back Check Self Test System
The Back Check self-test system that has been acquired performs real-time reverse calculation while transmitting and converting signals from the transmitter to confirm and detect the correctness of the calculations.
