In-situ calibration of temperature sensors
On-site calibration functionality without sensor removal
Temperature sensors age. Subjected to certain stress, they can suffer from drift of a few degrees over time. To maintain their initial accuracy in the long term, temperature sensors require frequent recalibration. This is a time-consuming effort as the sensors need to be removed from the process. Dismounting and reinstallation may also damage them, affecting process safety in the end.
OPTITEMP temperature sensors with in-situ calibration functionality allow for a calibration under process conditions using a calibrated reference sensor that is plugged into the installed sensor on-site to determine the measurement deviation. This makes calibration more efficient and accurate while minimising the risk of sensor errors and damages.
