Differential Pressure Transmitter
Yokogawa EJA210A and EJA220A Flange Mounted Differential Pressure Transmitter
The high performance differential pressure transmitter models EJA210A and 220A can be used to measure levels of densities. Both output a 4 to 20 mA DC signal corresponding to the measured differential pressure. Models EJA210A and 220A also feature remote setup and monitoring.
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.
