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.
