Description

The model TR22-A resistance thermometer is used for temperature measurement in sanitary applications. The process connections meet the stringent requirements, in terms of materials and design, of hygienic measuring locations. With increased hygienic requirements for the ambient areas around the measuring location, a stainless steel head is available in an optimised hygienic design. This enables easy cleaning of the measuring instrument, particularly for splash zones in food production. Due to the rotatable threaded connection to the connection head, it is possible to loosen the connection head and to adjust it in the desired position. The connection head can be removed together with the measuring insert. This allows the resistance thermometer to be calibrated along with the whole measuring chain, i.e. without disconnecting the electrical connections. In addition, this avoids having to open the process, and thus the risk of contamination is minimised. 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 welded junction between the protection tube and the flange makes the use of a sealing as additional material in those areas redundant which are in contact with the product.
