The model TR22-B resistance thermometer is used for temperature measurement in sanitary applications. To integrate it into the process, the patented protection tube model TW61 (patent, property right No. DE 102010037994 and US 12 897.080) is directly orbitally welded into a pipeline.

The connection ends are smooth and prepared for orbital welding. The process connections meet the stringent requirements, in terms of materials and design, of hygienic measuring points.

For easy calibration or maintenance, the sensor is interchangeable without having to open the process or to disconnect the electrical connection. Thus hygiene risks can be minimised and downtimes can be reduced.

The spring-loaded measuring insert guarantees the contact between the sensor tip and the bottom of the protection tube and thus ensures a fast response time and high accuracy.
