EJX310B Wireless Pressure Transmitter
Brand: Yokogawa Electric CorporationThe high performance wireless pressure transmitter EJX310B features a single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam flow as well as liquid level, density, and pressure.
These transmitters transmit not only process variables but also the setting parameters using wireless signal. The transmitters run on internal batteries, and the installation cost can be decreased since hard-wiring is not required.
The communication is compliant with ISA100.11a protocol specifications.
Features- Long Life Battery Design
- Ultra low current consumption design using two high capacity lithium-thionyl chloride batteries provide wireless operation for years
- Security Assured Wireless Network Joining
- Infrared communication between the devices for wireless network configuration and parameter setting
- Quick Update Time
- Selectable from 0.5 second to 60 minutes for measured process value to publish wirelessly
