Page 19: Chapter 3 Calibration
Calibration Sensor calibration The nominal cell constant of the Rosemount 225 sensor is 2.7/cm. The error in cell constant is about ±10%, so conductivity readings made the using the nominal cell constant will have an error of at least ±10%. Wall effects,as shown in... - Page 20 Calibration Reference Manual August 2018 00809-0100-3225 Procedure 1. Remove the sensor from the pipe. 2. Fill a container with the standard solution. If wall effects are absent in the process installation, use a sufficiently large container for calibration to ensure that wall effects are absent. To check for wall effects, fill the container with solution and place the sensor in the center, submerged at least 3/4 of the way up the stem.

Calibration Reference Manual August 2018 00809-0100-3225 Results Figure 3-4 shows the arrangement. Figure 3-4: Calibration with a referee instrument example Calibrating against a Referee - Grab Sample This method is useful when calibration against a standard is impractical or when in-process calibration is not feasible, because the sample is hot, corrosive, or dirty, making handling the waste stream from the referee sensor difficult. - Page 23 August 2018 3. Place the sensors in the grab sample. Wait until the readings are stable before starting the calibration. 4. Adjust the reading from the process analyzer to match the conductivity measured by the referee sensor. Rosemount 225 Sensors...
