The EJX110B is a high performance, wireless differential pressure transmitter that features a single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam pressure as well as liquid level, density, and pressure. These transmitters transmit the process variables and setting parameters using a wireless signal. They also run on internal batteries, greatly reducing the cost of installation as hard-wiring is not required. The communication is compliant with ISA100.11a protocol specifications.


  • Long Life Battery DesignUltra low current consumption design using two high capacity lithium-thionyl chloride batteries provide wireless operation for years.
  • Security Assured Wireless Network JoiningInfrared communication between the devices for wireless network configuration and parameter setting.
