Request Information
Favorite

Diaphragm seals are used to prevent process medium from entering directly into the pressure-sensing assembly of the differential pressure and pressure transmitters, they are connected to the transmitter using capillaries filled with fill fluid.

EJX118B Diaphragm Sealed Differential Pressure Transmitters can be used to measure liquid, gas, or steam flow, as well as liquid level, density and pressure.

EJX118B 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 protocol 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
