EJX530B Wireless Pressure Transmitter
Brand: Yokogawa Electric CorporationThe High performance absolute and gauge pressure transmitters EJX530B feature single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam pressure. EJX530B and 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
