Product Details

Eja430a Pressure Transmitter/Pressure sensor price

DESCRIPTION:
The EJA Series is available with BRAIN, HART, FOUNDATION TM fieldbus or PROFIBUS PA communication protocols.
The EJA Series is available with BRAIN, HART, FOUNDATION™ fieldbus or PROFIBUS PA communication protocols.
The high performance gauge pressure transmitter model EJA430A can be used to measure liquid, gas, or steam pressure. It outputs a 4 to 20 mA DC signal
corresponding to the measured gauge pressure.

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 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 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.
