EJX118A Diaphragm Sealed Differential Pressure Transmitter

Product Information

Diaphragm seals are used to prevent process medium form entering directly into the pressure-sensing assembly of the differential pressure transmitter, they are connected to the transmitter using capillaries filled with fill fluid.
EJX118A Diaphragm Sealed Differential Pressure Transmitters can be used to measure liquid, gas, or steam flow, as well as liquid level, density, and pressure.
The multi-sensing technology provides the advanced diagnostic function to detect such abnormalities as an impulse line blockage.

The EJX series is available with BRAIN, HART, and FOUNDATION™ fieldbus communication protocols.
