Page 3: Description And Specifications
Description and specifications 1.1 Toroidal conductivity sensors 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 eluents in chromatographic separations. - Page 4 Glass-filled PEEK 230 °F (110 °C) 200 psig (1480 kPa [abs]) Unfilled PEEK (meets 266 °F (130 °C) 21CFR177.2415 and 3A standard 74-06) Unfilled PEEK (meets USP Class VI standards) Unfilled Tefzel 230 °F (110 °C) www.Emerson.com...

Page 15: Calibration
3 Calibration 3.1 Sensor calibration The nominal cell constant of the Rosemount 225 sensor is 3.0/cm. The error in the cell constant after calibration can be +/- 10% of the nominal value. Wall effects (Figure 3-1), will likely make the error greater. - Page 16 Also, ensure that the orientation of the sensor with respect to the piping is exactly the same in the process and calibration vessels (see Figure 3-2). www.Emerson.com...

- Page 18 Ensure air bubbles are not adhering to the sensor. An air bubble trapped in the toroid opening severely effects the reading. 5. To eliminate error in the cell constant, turn off automatic temperature compensation in the transmitter. 6. Adjust the transmitter reading to match the conductivity of the standard. www.Emerson.com...
