A Reliable Sensor for High Conductivity Sanitary Applications

Rosemount 225 toroidal conductivity sensors are intended to be used in many pharmaceutical and food and beverage applications
where a sanitary design is required. These corrosion and fouling resistant sensors are ideal for measuring the concentration of CIP
solutions, detecting product/water interfaces, checking product quality, and monitoring eleuents in chromatographic separations.

Ordering Information

Rosemount 225 Sanitary Toroidal Conductivity Sensors work well in high conductivity
liquids up to 2 S/cm (2,000,000 µS/cm). These sensors include an integral Pt-100 RTD for

temperature compensation and 20 ft of integral cable. Cables can be extended using a remote
junction box PN 23550-00 (see Accessories).
