Yokogawa High Accuracy EJA430A Differential Pressure Transmitter
The EJA-A series is Yokogawa's most successful pressure transmitter
line. First released in 1991, it continues to offer high
performance and high reliability for any application. With an
installed base of over 4-1/2 million EJA-A transmitters worldwide,
it has a proven track record that makes it a true industry
workhorse.
The EJA430A is the Traditional-mount Differential Pressure
Transmitters in the series.
EJA430A features include:
- 0.065% Accuracy
- 0.1% Stability per 5 years
- 2,300 psi MWP
The high performance differential pressure transmitter model
EJA430A can be used to measure liquid, gas, or steam flow as well
as liquid level, density and pressure. It outputs a 4 to 20 mA DC
signal corresponding to the measured differential pressure.
The EJA Series is available with BRAIN, HART, FOUNDATION fieldbus
or PROFIBUS PA communication protocols.
Features:
-- 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.
-- 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 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
