PUR-SENSE™ Model 225 Toroidal Conductivity Sensor

---

REDUCED CLEANING REQUIREMENTS provided through the use of inductive measuring principles. CHEMICALLY RESISTANT MATERIALS withstands the effect of highly corrosive solutions. HIGH TEMPERATURE PEEK SENSOR operates at temperatures up to 200°C (392°F). MODEL 225 SENSOR AVAILABLE unfilled PEEK and USP Class VI unfilled PEEK. Sensor meets 3A sanitary standards.

FEATURES AND APPLICATIONS Rosemount Analytical Toroidal Conductivity Sensors are used in processes where conventional sensors having electrodes exposed to the measured solution would corrode or become fouled. The Model 225 conductivity sensor consists of a pair of wire-wound metal toroids overmolded with corrosion-resistant PEEK or Tefzel. One coil is the transmitter, and the other coil is the receiver. When the sensor is immersed in a conductive liquid and the transmitter coil is energized, the coil induces a current in the solution. The solution current induces another current in the receiver coil, which the analyzer measures. The current in the receiver coil is directly proportional to the conductivity of the solution. The Model 225 CIP Sensor is designed for the pharmaceutical and food & beverage industries. The sensor is available with a two-inch Tri-Clamp® fitting.
