Detailed introduction
The Yokogawa EJA310E high-performance absolute pressure transmitter is a common high-performance absolute pressure transmitter following the EJA series from Chongqing Chuan Yi Yokogawa. It utilizes Yokogawa's most advanced single crystal silicon resonant sensing technology, making it very suitable for measuring the flow, liquid level, density, and pressure of liquids, gases, or steam. Its performance and reliability have been enhanced, and it comes with built-in safety certification. Its small form factor and robust materials meet Yokogawa's stability requirements for its products. The working principle of the Yokogawa EJA310E high-performance absolute pressure transmitter is to convert the measured pressure into a 4-20mA DC current signal output, allowing for the measurement, display, or remote monitoring of static pressure, with features such as fast response, remote setting, and self-diagnosis. The EJA-E series supports BRAIN, HART/HART (1-5V) low power consumption, and FOUNDATION™ fieldbus or PROFIBUS PA communication protocols.
