Yokogawa EJA/EJX Series Differential Pressure Transmitter With
Fieldbus Communication
product description
The high performance differential pressure transmitter FJA 11OE
uses a single crystal silicon resonant sensor and is suitable for
measuring the flow of liquid, gas or steam as well as the level,
density and pressure. The EVA110E outputs a DC signal of 4 to 20
mA, corresponding to the measured differential pressure. Its
sensors are accurate and stable, and can also measure static
pressure, which can be displayed on integral indicators, or
monitored remotely by BRAIN or HART communication. Other key
features include fast response, remote Settings using communication
and self-diagnosis. Foundation fieldbus, PROFIBUS PA and 1 to 5 V
DC with HART(low power) protocol types are also available. With the
exception of the fieldbus, PROFIBUS, and low-power types, the EJA-E
series models follow standard configurations that meet SIL 2 safety
requirements.
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)
peculiarity
Digital sensor
DPharp digital sensors directly output digital signals without the
need for digital conversion of analog signals, reducing errors and
providing accurate, reliable and stable measurement performance.
Rugged construction
Rugged construction helps reduce breakdowns in your factory.
Four-bolt pressure-holding design, DPharp digital sensor, Teflon
coated 316L stainless steel flange washer, ANSI/ISA 12.27.01
certified double seal -- all design features for extended
transmitter life.
overvoltage protection
Not only is the DPharp sensor's rugged design resistant to
overpressure, but the mechanical design inside the capsule further
provides overpressure protection against overpressure events such
as incorrect valve bank operation and unexpected pressure surges.
Accuracy Under All Operating Conditions
Yokogawa's DPharp sensor has the ability to measure differential
pressure (DP), static pressure (SP) and sensor temperature from a
single sensor. Given these three sets of process data, Yokogawa's
transmitter can compensate DP measurements of temperature effects
and static pressure effects in real time. This is called dynamic
compensation and improves the accuracy of DP measurements.
Extended Calibration Intervals
The long-term stability of the EJA-E series allows you to extend
the interval time between calibration and reduce the time cost and
maintenance cost.
