Based on the information available, the YOKOGAWA A5E0023936304 is likely the part number for the EJA530E In-Line Mount Gauge Pressure Transmitter. Here is the detailed information in English:
The EJA530E is a high-performance gauge pressure transmitter developed by Yokogawa. It is designed to accurately, quickly, and reliably measure the pressure of liquids, gases, or steam, and convert the pressure into a 4-20mA DC current signal for output. It also has functions such as fast response, remote setting, and self-diagnosis.

- Digital Sensor: The DPharp digital sensor directly outputs a digital signal without the need for analog-to-digital conversion, reducing errors and providing accurate, reliable, and stable measurement performance.
- 10-Point Signal Curve Characterization: The EJA-E series transmitters have a 10-point signal curve characterization function, which is suitable for compensating the 4-20mA analog output signal in non-linear applications. It can be used in all applications where the corresponding relationship between the input pressure and the output signal is clear, such as tank measurement and flow measurement, making the measurement more flexible and convenient.
- Built-in Display: The built-in display of the EJA-E series transmitters can display all measurement data, as well as alarm codes and bar charts, etc., and can also be programmed according to your needs. In addition, the display runs on a separate circuit, independent of the output signal, and will not be affected by it.
- Self-Diagnosis Function: The EJA-E series transmitters have 40 self-diagnosis functions, two of which are unique features. One is the Back-Check patented technology, which confirms and detects the correctness of the calculation through real-time reverse calculation. The other is that the DPharp is an active sensor. Even if the input pressure does not change, the sensor will continuously output the corresponding signal. When the sensor signal is interrupted, the transmitter can detect the sensor failure at the first time.
- Safety Certification: The EJA-E series transmitters are designed and certified according to the IEC61508:2010 (parts 1-7) and IEC61511:2004 (parts 1-3) standards. A single transmitter meets the SIL2 safety requirements, and redundant use meets the SIL3 safety requirements.
