EJX210B Wireless Pressure Transmitter

Brand: Yokogawa Electric Corporation

The high performance flange mounted differential pressure transmitter EJX210B features single crystal silicon resonant sensor and is suitable to measure levels of densities of solidifying or precipitating liquids.

EJX210B transmits not only process variables but also the setting parameters using wireless signal. The transmitter runs on internal batteries, and the installation cost can be decreased since hard-wiring is not required.

The communication protocol is compliant with ISA100.11a protocol specifications.
