Description

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.

Model TR22-B with flow-through housing for orbital welding

Options: Sealing combination at neck tube, cable gland in hygienic design

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.

The use of uniform measuring insert lengths, even for different nominal widths of pipes, reduces the inventory of the measuring inserts, particularly for larger plants. Additionally, the measuring insert length is optimised for an on-site calibration, for example with aWIKA temperature dry-well calibrator model CTD9x00.

Process connection
Sealing combination (option)Transition from the connection head to the protection tube is effected via an optional sealing combination (polyurethane) of flat gasket and wiper
■ Permanently prevents the penetration and depositing of humidity and impurities in this area (IP68) ■ Simplifies cleaning considerably (in combination with the patented BVS head and the hygienic cable gland, an easy to clean and hygienic measuring location results,
even in areas which are not in contact with the product)
Patented hygienic design (for flow-through housing)■ Dead-space minimised, invasive temperature measurement ■ Flexible mounting position due to self-draining ■ With horizontal installation, make sure that the pipeline is slightly inclined for self- draining ■ The installation is carried out by means of orbital welding; thus, the weld seams are reproducible and controllable
