The model TR22-B resistance thermometer is used for temperature measurement in sanitary applications. For an integration into the process the patented thermowell model TW61 is directly fitted into a pipeline by means of orbital welding.

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

The sensor is removable without having to break into the process or disconnect the electrical connection. This is for easy calibration or maintenance. 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 thermowell and thus ensures a fast response time and high accuracy.
