Diaphragm seal is used to
prevent process medium from entering directly into the
pressure-sensing assembly of the pressure transmitter. It is
connected to the transmitter using capillary filled with fill
fluid. Models EJA**8W and EJA**8N Diaphragm Sealed Gauge Pressure
Transmitters can be used to measure liquid, gas or steam pressure.
They output a 4 to *0 mA DC signal corresponding to the measured
pressure.
The EJA Series is available
with BRAIN, HART, FOUNDATION™ fieldbus or PROFIBUS PA communication
protocols.
Product Features
Excellent
performance and
stability
The EJA series uses a silicon
resonant sensor formed from monocrystal silicon, a perfect material
which has no hysteresis in pressure or temperature changes. The
sensor minimizes overpressure, temperature change, and static
pressure effects, and thus offers unmatched long-term
stability.
Compact and
light-weight
design
Half the weight of
conventional models thanks to miniaturization of the casing with
the amplifier ASIC, pressure cell structure, and flange. The ASIC
uses the minimum number of parts and improves the reliability of
the amplifier.
Fieldbus
communication
capability
Fieldbus is a digital two-way
communication system. It is a revolutionary technology for
configuring instrumentation control systems and a promising
successor to the standard 4 to *0 mA analog communication used in
most field instruments today.
EJA series offers two types of
fieldbus models, FOUNDATION™ fieldbus Low Voltage Mode and PROFIBUS
PA devices, which ensure interoperability between Yokogawa and
other manufactures. As for software, the EJA series incorporates
two AI function blocks that compute differential and static
pressures to allow flexible configuration of
instrumentation.
