Yokogawa EJA430E 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.

The EJA-E series transmitter has 40 self diagnostic functions, two of which are its unique features. One is the patented Back Check technology, which uses real-time reverse calculation to confirm and detect the correctness of calculations. Secondly, DPharp is an active sensor that continuously outputs corresponding signals even if the input pressure remains unchanged. When the sensor signal is interrupted, the transmitter can detect the sensor failure in the first time. When passive sensors have no signal output, they cannot determine whether it is due to no change in pressure or sensor failure.

The functional features of EJA430E 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.
