Yokogawa EJA510A Absolute Pressure Transmitter

General Description:

The Yokogawa EJA510A is a high-performance absolute pressure transmitter measuring liquid, gas, or steam pressure1. It utilizes a DPharp digital sensor to offer accuracy and stability3. The transmitter outputs a 4 to 20 mA DC signal corresponding to the measured pressure14. It also allows for remote setup and monitoring through communication with devices and systems like the BRAIN™ terminal, CENTUM CS™, or µXL™1.
