SI315.1 TOROIDAL CONDUCTIVITY SENSOR

ST315, Measuring range 0 to 2,000 mS, extendable and submersible. Working range 0 to 40°C

The ST 315.21 toroidal conductivity sensor from B&C Electronics is an advanced solution for accurate conductivity measurement in industrial liquids. Its electrodeless technology, based on toroidal coils, eliminates common problems such as electrode contamination and polarization, ensuring reliable measurements even under demanding conditions.
Designed for submersible installations (IP68) and constructed of durable PVC, this sensor withstands corrosive liquids and harsh conditions. It incorporates a Pt100 temperature sensor for thermal compensation and a model 080315 microtransmitter, optimizing signal transmission. It operates at temperatures up to 40°C and pressures up to 3 bar at 25°C, making it ideal for immersion applications.
It is fully compatible with the C 565.2 and C 7685 controllers and comes with optional accessories such as the SZ 9481 (10 m) and SZ 9483 (30 m) cables with IP67 connectors. ISO 9001:2015 certified, this sensor stands for quality and durability in industrial conductivity measurement.
