Foxboro 871FT Industrial Electrodeless and Flowthrough Conductivity Sensor

871FT Conductivity Sensor

The Foxboro 871FT is a non‑invasive, flow‑through electrodeless (toroidal) conductivity sensor suitable for industrial and sanitary process fluids. It is designed to operate with transmitters such as the 876EC, 875EC, or 873EC series. Its built-in inline calibration port, wide material compatibility, and sanitary certifications make it ideal where sensor access is limited or line integrity must be maintained.
