Temperature measurements are the most common measurements in the process industry.
The increased requirements for process safety have led to an ever increasing number of measurement points in recent years. However, the accuracy of every measurement must be confirmed by regular calibration.
Temperature measurements with Pt 100 elements have proven to be very robust and reliable. These sensors are very rarely replaced due to insufficient calibration results.
For a calibration, the measurement device is compared with a reference sensor with a known, high level of accuracy.
For the calibration of a temperature measurement device, the challenge is to bring the sensor element and reference to the exact same temperature. The level of effort to achieve this depends on the required accuracy. Typically, special calibrators are used. Either the temperature sensors are removed and measured in the calibration laboratory, or the calibration is performed using a mobile calibrator on-site on the production floor. However, the measurement device must be taken out of the process in this case as well.
