The built-in display meter of the EJA-E transmitter can display all measurement data, as well as alarm codes and bar charts, and can also be programmed according to your needs. In addition, the display meter operates on a separate circuit, independent of the output signal, and will not be affected by it. 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.
