Yokogawa EJX118A Diaphragm Sealed Differential Pressure Transmitter

Diaphragm seals are used to prevent process mediumform entering directly into the pressure-sensingassembly of the differential pressure transmitter, theyare connected to the transmitter using capillaries filedwith fil flid.
EJX118A Diaphragm Sealed Differential PressureTransmitters can be used to measure liquid, gas,or steam flw, as well as liquid level, density, andpressure. EJX118A outputs a 4 to 20 mA DC signalcorresponding to the measured differential pressure.
Its highly accurate and stable sensor can alsomeasure the static pressure which can be shown onthe integral indicator or remotely monitored via BRAINor HART communications. Other key features includequick response, remote set-up using communications,and diagnostics and optional status output forpressure high/low alarm. The multi-sensing technology
provides the advanced diagnostic function to detectsuch abnormality as an impulse line blockage.FOUNDATION Fieldbus and PROFIBUS PA protocoltypes are also available. All EJX series models intheir standard confiuration, with the exception of the
Fieldbus and PROFIBUS types, are certifid by TÜVas complying with SIL 2 for safety requirement.
