Yokogawa Liquid Level transducer EJA 210A
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 EJA210A and EJA220A are Flange-mount Liquid Level Transmitters in the series.
Key EJA210A and EJA220A feature include:
§ 0.075% Accuracy
§ 0.1% Stability per 5 years
§ Flush Flange Process Connection (EJA210A)
§ Extended Flange Process Connection (EJA220A)
Yokogawa's Liquid Level Transmitter with DPharp digital sensor offers the performance and device intelligence needed to get greater insight into your process.
Plants run better with Yokogawa pressure transmitters.
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.
