Pressure Transmitter
Yokogawa EJA310A Absolute 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 EJA310A is a Traditional-mount Absolute Pressure Transmitter in the series.
EJA310A features include:
- 0.15% Accuracy (0.075% Option)
- 0.1% Stability
- External Zero Adjust
Pressure Transmitter
Yokogawa EJA310A Absolute Pressure Transmitter
The high performance gauge pressure transmitter model EJA310A can be used to measure liquid, gas, or steam pressure. It outputs a 4 to 20 mA DC signal corresponding to the measured absolute pressure.
Model EJA310A also features remote setup and monitoring through communications with the BRAIN™ terminal and CENTUM-CS™ or XL™ or HART® 275 host.
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.
