B&C Electronics ST 3254.X & ST 3214.X Electrodeless Conductivity Sensors

The B&C Electronics ST 3254.X & ST 3214.X Electrodeless Conductivity Sensors feature built-in temperature compensation, a 4-20 mA loop-powered transmitter, and multiple ranges for water treatment and monitoring applications.

The B&C Electronics ST 3254.X and ST 3214.X Electrodeless Conductivity Sensors combine a 4-20 mA loop-powered transmitter with a toroidal conductivity sensor in one compact unit. These sensors include built-in temperature compensation and are available in six models covering ranges from 0–10 mS to 0–2000 mS, with an optional 0–300 mS version available on request. Using an electrodeless measurement method, they avoid contamination and polarization problems common with conventional electrode systems. This design provides stable and accurate readings, making them ideal for water treatment, cooling towers, and general water monitoring applications. Find the ST 3254.X and ST 3214.X sensors at Hinco in Perth, WA for reliable conductivity measurement.
