YOKOGAWA EJA110A Differential Pressure Transmitter

 

EJA110A Differential Pressure Transmitter

The high-performance EJA110A differential pressure transmitter can be used to measure liquid, gas, or steam flow as well as liquid level, density and pressure.

Product Information
The high performance differential pressure transmitter model EJA110A 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 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.
