Yokogawa DPharp EJA220 Flange Mounted Differential Pressure Transmitter

The Yokogawa DPharp EJA220 is a high-performance flange-mounted differential pressure transmitter designed for accurate level, flow, and pressure measurement in industrial applications such as petrochemical, oil and gas, and water treatment processes. It features Yokogawa's proprietary DPharp sensor technology, which provides superior stability, overpressure protection, and resistance to harsh environments, outperforming traditional analog sensors with digital accuracy up to 0.075% of span. Key benefits include robust construction with stainless steel wetted parts for corrosion resistance, easy installation via flange mounting, and compatibility with HART communication protocols for seamless integration into control systems. Drawbacks may include higher initial cost compared to basic transmitters and the need for periodic calibration in extreme conditions. This model excels in tank level monitoring, offering advantages like minimal drift over time and high turndown ratios, making it more reliable than competitors like Rosemount or Endress+Hauser in demanding setups. Based on attached images, the unit appears used but in good condition, with visible faceplate details including model EJA220, serial numbers (e.g., 91K202), and ratings like 0-100 m calibration range. No major damage observed; includes manifold and flange assembly as child assets. Estimated market price for a used unit: $800-$1200 USD.
