Diaagm 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.
Yokogawa Model EJA118W, EJA118N and EJA118Y Diaagm 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 ding to the measured differential pressure.
The EJA series is available with BRAIN, HART, FOUNDATION⢠field bus or PROFUSE PA communication protocols.
