Yokogawa EJA510A Direct Installation Type Absolute Pressure Transmitter
Details:
Yokogawa EJA510A direct mount absolute pressure transmitter is mainly used to measure the pressure of gases, liquids, and steam, and then convert it into a 4- 20mA DC signal output. As we all know, the EJA smart transmitter is the latest product launched by Yokogawa Electric Corporation in Japan, which first adopts a digital sensor - a single-crystal silicon resonant sensor. The sensor outputs a pair of differential digital signals, directly eliminating external interference in the sensor part, creating a new era for transmitters. The product has higher accuracy (±0.075%), higher stability, and reliability, and has received widespread acclaim since its market launch.
