EJX110A Differential Pressure Transmitter
The high performance differential pressure transmitter
EJX110A features single crystal silicon resonant
sensor and is suitable to measure liquid, gas, or
steam fl ow as well as liquid level, density and
pressure. EJX110A outputs a 4 to 20 mA DC signal
corresponding to the measured differential pressure.
Its highly accurate and stable sensor can also
measure the static pressure which can be shown on
the integral indicator or remotely monitored via BRAIN
or HART communications. Other key features include
quick response, remote set-up using communications,
diagnostics and optional status output for pressure
high/low alarm. The multi-sensing technology provides
the advanced diagnostic function to detect such
abnormalities as an impulse line blockage or heat
trace breakage. FOUNDATION Fieldbus and PROFIBUS
PA protocol types are also available. All EJX series
models in their standard confi guration, with the
exception of the Fieldbus and PROFIBUS types, are
certifi ed by TüV as complying with SIL 2 for safety
requirement.
