In-process calibration procedure

The regular monitoring and verification of an ever-increasing number of measurement points takes a great deal of time and money. For temperature measurement points with medium or low accuracy requirements, a specialised calibration procedure and appropriately designed measuring instruments can significantly reduce the effort involved and, in particular, downtime.

The challenge with calibration is bringing the sensor element and the reference to the same temperature. The effort involved depends on the accuracy requirements. For conventional calibration, the temperature sensors must be removed and measured in the calibration laboratory or using a portable calibrator.

The reference probe is used to calibrate resistance temperature detectors for in-process calibration. This requires a special measuring insert with a test tube. This allows the built-in resistance temperature detector to be calibrated without removing the measuring insert.

Highlights

• Regular monitoring and inspection of multiple measurement points
• Significantly reduce downtime
• No need to remove the temperature sensors
