YOKOGAWA ISC202S INDUCTIVE CONDUCTIVITY TRANSMITER 2-WIRE ISC202S-F-E

Description:

The Yokogawa ISC202S-F-E Inductive Conductivity Transmitter is used in industrial process systems to measure liquid conductivity and transmit a 4–20 mA signal for monitoring and control. Commonly installed in chemical processing, water treatment, and industrial plants where accurate conductivity and concentration measurement is required. Maintenance teams, OEMs, and system integrators use this transmitter for process monitoring, replacement of legacy analyzers, and ensuring stable measurement in harsh environments.

Applications:

The Yokogawa ISC202S-F-E is used in industrial liquid analysis systems for measuring conductivity in medium to highly conductive fluids. It is commonly deployed in chemical plants, pulp and paper mills, metal finishing operations, and food processing systems where inductive measurement is preferred for handling corrosive or fouling liquids. The transmitter is typically paired with ISC40 sensors and supports reliable operation in aggressive process conditions.
