11. The conductivity sensor incorporates a fixed precision resistor in parallel with the cell When the cell is dry and in air the sensor s electrical circuitry outputs a frequency representative of the fixed resistor This frequency is recorded on the Calibration Certificate and should remain stable within 1 Hz over time The primary mechanism for calibration drift in conductivity sensors is the fouling of the cell by chemical or biological deposits Fouling changes the cell geometry resulting in a shift in cell constant Accordingly the most important determinant of long term sensor accuracy is the cleanliness of the cell We recommend that the conductivity sensors be calibrated before and after deployment but particularly when the cell has been exposed to contamination by oil slicks or biological material Temperature Sensor Calibration The primary source of temperature sensor calibration drift is the aging of the thermistor element Sensor drift will usually be a few thousandths of a degree during the first year and less in subsequent intervals Sensor drift is not substantially dependent upon the environmental conditions of use and unlike platinum or copper elements the thermistor is insensitive to shock Pressure Sensor Calibration The SBE 16plus is available with a strain gauge pressure sensor or Quartz pressure sensor These sensors are capable of meeting the SBE 16plus error specification with some allowance for agin
