Differential Pressure Transmitter
Yokogawa EJA120A Draft Range Differential 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 EJA120A is the traditional-mount Draft Range Pressure transmitter in the series.
Key EJA120A features include:
- 0.2% Accuracy (0.1% Accuracy available with /HAC option)
- 300 msec Response Time (with /F1 option)
- True Draft Range design
Differential Pressure Transmitter
Yokogawa EJA120A Draft Range Differential Pressure Transmitter
The high performance draft range differential pressure transmitter model EJA120A outputs a 4 to 20 mA DC signal corresponding. Yokogawa model EJA120A also features remote setup and monitoring through communications.
Features:
- Excellent performance and stability
The EJA series uses a formed from monocrystal silicon, a perfect material. 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.
