Remote Seals

Diaphragm seals are used to prevent process medium from entering directly into the pressure-sensing assembly of the differential pressure transmitter. Yokogawa has two models of Diaphragm Sealed Gauge Pressure Transmitters. Models EJA118N, EJA118W, and EJA118Y can be used to measure liquid, gas, or steam flow, as well as liquid level, density, and pressure. Models EJA438N and EJA438W can be used to measure liquid, gas, or steam pressure. Both 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 BRAIN terminal and CENTUM CS or µXL or HART host.
