EJA110E transmitter 4-20mA Yokogawa Differential Pressure
Transmitter
The EJA-E series of transmitters is Yokogawa's most recent
evolution of the DPharp family of pressure transmitters. Released
in 2012, it combines the ruggedness and success of the work-horse
EJA-A series with the performance of the thoroughbred EJX-A series
to deliver the type of product you have come to expect from
Yokogawa.
EJA110E features include:
- 0.055% Accuracy (0.04% Accuracy optional)
- 0.1% Stability per 10 years
- 90 ms Response Time
- Exida and TUV SIL 2 / SIL3 Certified
- MWP 2,300 psi (MWP 3,600 psi option)
- Local Parameter Setting (LPS)
Yokogawa's DPharp sensor has the ability to measure the
differential pressure (DP), static pressure (SP), and sensor
temperature from a single sensor. Giving these three pieces of
process data, Yokogawa's transmitter can compensate the DP
measurement for Temperature Effect and Static Pressure Effect in
real time. This is referred to as Dynamic Compensation and improves
the DP measurement accuracy.
Competitor's analog sensors can only measure DP and Sensor
temperature. So, theirs can compensate for temperature Effect; but,
since the SP measurement is missing, it cannot compensate for
Static Pressure Effects.
Save up to 20% on CAPEX spending using the DPharp's multi-sensing
capability. With our competitor's transmitters using analog
sensors, any application that requires measurement of both
differential pressure (DP) and static pressure (SP) requires two
separate transmitters - one to measure the DP and one to measure
the SP. Yokogawa's differential pressure transmitter with
multi-sensing DPharp sensor, can measure both process variables (DP
and SP) with a single transmitter. Two transmitters will always
cost more than one transmitter.

Features:
1-- Excellent performance and stability
The EJA series uses a 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.
2-- 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.
3-- 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 20 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 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.
