YOKOGAWA ISC402G INDUCTIVITY CONDUCTIVITY CONVERTER EXA SERIES

Description:

The Yokogawa ISC402G Inductive Conductivity Converter is used in industrial process systems to measure liquid conductivity and convert it into analog signals for monitoring and control. Commonly installed in chemical processing, water treatment, and industrial plants where accurate conductivity measurement is required for concentration control. Maintenance teams, OEMs, and system integrators use this converter for process monitoring, system upgrades, and replacement of legacy conductivity analyzers.

Applications:

The Yokogawa ISC402G is used in industrial liquid analysis systems for measuring conductivity in corrosive, fouling, or high-conductivity process fluids. It is commonly deployed in chemical plants, pulp and paper mills, metal finishing operations, and wastewater treatment systems. The converter works with inductive sensors such as ISC40 and is ideal for applications involving acids, alkalis, and salt solutions where non-contact measurement ensures long-term stability and reduced maintenance.
