YOKGAWA EJA118W, EJA118N, EJA118Y Diaphragm Sealed Differential Pressure Transmitters
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 YOKOGAWA EJA118W, YOKOGAWA EJA118N and YOKOGAWA 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 differential pressure.
The YOKOGAWA EJA Series is available with BRAIN, HART, FOUNDATION™ fieldbus or PROFIBUS PA communication protocols.
