ABB TB4611E200002 Industrial Conductivity Sensor

ABB TB4611E200002 Industrial Conductivity Sensor is a rugged four‑electrode conductivity probe designed for inline, immersion, or retractable service in demanding process streams, featuring 316 stainless steel electrodes and interchangeable tip configurations. It provides a wide measurement range from 0 to 2,000,000 μS/cm, enabling accurate tracking from ultrapure or clean process waters to highly conductive streams, with integral temperature compensation options to improve stability across varying process temperatures. The sensor is rated for a maximum operating temperature of up to 200°C (392°F), and, for hot‑tap variants, supports high pressures (up to 1,550 kPa / 15.5 bar at 200°C) to accommodate aggressive industrial environments. Mounting options include in‑line insertion, immersion, and hot‑tap (retractable) configurations, with lengths available for hot‑tap installations in 16, 24, 30, and 36 inches, depending on the hardware and installation needs. Hardware selections cover hand‑tight 316 stainless steel with Viton O‑rings, wrench‑tight 316 stainless steel with Viton O‑ring, and flush/drain housings in 11/2 in NPT, with alternatives that use Kalrez O‑rings for higher‑temperature or chemically aggressive applications. The TB461 family is designed for full‑spectrum conductivity measurement in challenging industrial environments, offering a robust, interchangeable tip design to optimize performance across different process streams and installation geometries. Overall, this ABB sensor delivers precise conductivity readings across wide ranges, reliable operation in high‑temperature processes, and flexible mounting options to suit a variety of industrial water analyses.
