Yokogawa Differential Pressure Transmitter
Product Description
Yokogawa Differential Pressure Transmitter EJX110A
Yokogawa EJX Series transmitter released in 2004, owns premium performance compare to EJA series like fast response to 95ms, long stability +/- 0.1% of URL for 10 years, Impulse line blockage detection, higher static work pressure and etc; which offers the most technologically advanced solution with class-leading performance and stability specifications. Additionally, the EJX also offers unique features such as standard IEC61508 certification, optional contact output, advanced diagnostics, multivariable mass flow measurement and ISA100 wireless capability.
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 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.
