Wireless Differential Pressure/Pressure Transmitters

What Is a Wireless Differential Pressure Transmitter?

High performance wireless differential pressure transmitters 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.

Yokogawa's EJX-B series transmitters combine the features on our thoroughbred EJX-A series with ISA100 wireless communication to deliver new opportunities and possibilities.

All Yokogawa ISA100 compliant products can integrate into any ISA100 compliant network.
