Foxboro 823DP-I3S1NL2 Differential Pressure Transmitter

The Foxboro 823DP-I3S1NL2 is a robust electronic differential pressure transmitter designed for precise measurement in industrial applications such as process control, flow monitoring, and level detection in sectors like oil and gas, chemical processing, and water treatment. Featuring a durable 316 stainless steel construction, it offers excellent corrosion resistance and reliability in harsh environments. Key benefits include high accuracy with a 4-20 mA output signal, wide supply voltage range (12.5-65 VDC), and a maximum working pressure of 3000 PSI, making it suitable for high-pressure systems. Compared to similar products like those from Rosemount or Yokogawa, the Foxboro model excels in its rugged design and ease of integration with legacy systems, though it may lack some modern digital communication protocols found in newer transmitters. Drawbacks include potential obsolescence in highly digitized setups, requiring adapters for advanced networks. This unit appears used based on visible wear, scratches, and minor discoloration in the provided images, but remains functional with intact faceplate details including model number, calibration range (0-3000 PSI), and certifications. No parent/child assets are evident.
