EJA118N Diaphragm Sealed Differential pressure transmitter
Features :
Yokogawa 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.
Specifications :
