Yokogawa Differential Pressure Transmitter EJX110A-EMS4G-917DB/KU22
The high performance Yokogawa Differential Pressure Transmitter EJX110A-EMS4G-917DB/KU22 features single crystal silicon resonant
sensor and is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure.
Yokogawa Differential Pressure Transmitter EJX110A-EMS4G-917DB/KU22 outputs a 4 to 20 mA DC signal
corresponding to the measured differential pressure.
Yokogawa Differential Pressure Transmitter EJX110A-EMS4G-917DB/KU22, 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 configuration, with the
exception of the Fieldbus and PROFIBUS types, are
certified by TÜV as complying
with SIL 2 for safety requirement.

Optional Codes

/ Optional specification
|
The “►” marks indicate
the most typical selection for each specification.
*1: Users must consider
the characteristics of selected wetted parts material and the influence of process
fluids. The use of
inappropriate materials can result in the leakage of corrosive process fluids and cause injury to personnel and/or damage
to
plant facilities. It is also possible that the diaphragm itself can be damaged and that material from the broken diaphragm
and
the fill fluid can contaminate the user’s process fluids.
Be very careful
with highly corrosive process fluids such as hydrochloric acid, sulfuric acid, hydrogen sulfide, sodium hypochlorite, and high-temperature steam (150°C [302°F] or above). Contact Yokogawa
for detailed information of the
wetted parts material.
*2: Only applicable
for Wetted parts material
code S.
*3: Not applicable
for measurement span code F.
*4: Not applicable
for electrical connection code 0, 5, 7, 9 and A. Content
rate of copper in the material is 0.03% or less and
content rate of iron is 0.15% or less.
*5: Not applicable
for electrical connection code 0, 5, 7 and 9.
*6: Material
of a blind plug is aluminum
alloy or 304 SST.
*7: Not applicable
for output signal code G.
*8: Not applicable
for output signal code F.
