EJA118Y Diaphragm Sealed Differential Pressure Transmitter

Brand: Yokogawa Electric Corporation

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. 

Model EJA118W, EJA118N and EJA118Y Diaphragm Sealed Differential Pressure Transmitters can be used to measure liquid, gas, or steam flow, as well as liquid level, density, and pressure.

They output a 4 to 20 mA DC signal corresponding to the measured pressure differential. 

The transmitters also feature remote setup and monitoring through communications with the model BT200/100 BRAIN TERMINAL, CENTUM CS/XL system etc.
