ABB Two-Electrode Sensors (TB2/AC200)
Two-electrode contacting conductivity sensors designed for precise measurement across a broad range—from 0 to 10,000 µS/cm, and up to 20,000 µS/cm when paired with TB82TE analyzers. These sensors deliver high-accuracy performance for applications ranging from ultrapure water to industrial rinse systems.
Using an AC signal applied between two electrodes immersed in the process fluid, the sensor detects the resulting voltage change. The connected transmitter then interprets this signal to provide reliable conductivity, concentration, or specific resistance readings, ensuring stable and repeatable process monitoring.
