Pressure Transmitter

Yokogawa EJA510A and EJA530A Absolute and Gauge 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 EJA530A is the In-line mount Gauge Pressure Transmitters in the series.

EJA530A features include:

  • 0.2% Accuracy (0.075% Option)
  • 0.1% Stability for 1 year
  • 8,500 psi MWP

Pressure Transmitter

Yokogawa EJA510A and EJA530A Absolute and Gauge Pressure Transmitter

The EJA Series is available with BRAIN, HART, FOUNDATION™ fieldbus or PROFIBUS PA communication protocols.

The absolute pressure transmitter model EJA510A can be used to measure liquid, gas, or steam pressure. Both output a 4 to 20mA DC signal corresponding to the measured pressure.

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.
