Product Details:

FOXBORO 873EC is a microprocessor-based intelligent conductivity transmitter, a robust analytical transducer designed for process automation. This transmitter is compatible with FOXBORO 871EC series electrodeless conductivity sensors, forming a complete on-line liquid conductivity measurement system. It adopts a rugged IP65 field mount housing, which protects internal precision electronic circuits from dust, moisture, chemical vapors and vibration in harsh industrial field environments. The local LCD display and menu keys allow operators to view real-time conductivity, resistivity and temperature readings, configure measuring ranges and perform calibration operations directly on site.

This FOXBORO 873EC analytical transducer receives raw inductive signals from the matched toroidal conductivity sensor. It calculates liquid conductivity and resistivity values with automatic temperature compensation to eliminate temperature drift impact and ensure stable and accurate liquid measurement. It supports standard 4~20mA isolated analog output and optional HART digital communication. Operators can remotely read measurement data, adjust parameters and access diagnostic information via HART communicator or DCS system. Built-in continuous self-diagnosis function monitors sensor connection status and internal circuit health. It will trigger alarm output when detecting cable breakage, sensor fault or hardware abnormality, helping maintenance engineers quickly locate faults and reduce unplanned plant downtime.
