Conductivity Measurement in Chemical Separators
Easy, reliable measurement of critical process parameter
Accurate Conductivity Measurement Even When Sensor is Coated
A conductivity sensor is used to detect whether the water phase or the organic phase is present at the measurement point in chemical processing separators. When the level of the water reaches the sensor, the controller opens a valve to discharge the water phase. Solids can build up in the water phase, coating the sensor and providing inaccurate or unresponsive measurements. The Rosemount™ 228 Toroidal Conductivity Sensor is an ideal choice for most separator applications because its electrodeless design provides an accurate and reliable measurement even as the sensor becomes coated by oils or suspended solids in the process.

Product Solutions
The Rosemount 228 Toroidal Conductivity Sensor reliably measures conductivity in highly conductive electrolyte solutions up to 2 S/cm (2,000,000 µS/cm). These conductivity sensors work in dirty and corrosive applications where metal electrode sensors would otherwise fail. A robust sensor design makes the Rosemount 228 conductivity sensor ideal for measuring concentrations of acid, base and salt solutions.
