Detailed introduction
The Yokogawa EJA510E high-performance absolute pressure transmitter is a high-performance direct insertion threaded absolute pressure transmitter among the E-series products of Chongqing Chuan Instrument Yokogawa transmitters. It adopts the latest single crystal silicon resonant sensor technology, mainly suitable for pressure measurement of liquids, gases, or steam. The Yokogawa EJA510E high-performance absolute pressure transmitter converts the measured pressure into a 4-20mA DC current signal output, featuring fast response, remote setting, self-diagnosis, and other functions. The Yokogawa EJA E-series transmitters provide communication protocols such as BRAIN, HART/HART (1~5VDC) low power type, FF fieldbus, and PROFIBUS PA, with standard configuration passing SIL 2 safety certification. The Yokogawa EJA-E series transmitters are the latest DPharp series launched by Yokogawa Electric Corporation in Japan. It was released in 2012, combining the robustness and success of the Yokogawa EJA-E series with the performance of the pure EJX-A series to provide the type of products you expect from Yokogawa.
