Description

The model TR21-C resistance thermometer provides temperature measurement in sanitary applications and can be used for the measurement of liquid and gaseous media in the range of -30 ... +250 °C [-22 ... +482 °F]. For use in hazardous areas, intrinsically safe versions are available. These thermometers are fitted with process connections that meet the stringent requirements, in terms of materials and design, of hygienic measuring points. All electrical components are protected against moisture (IP67 or IP69K). The resistance thermometer is available with direct sensor output or integrated transmitter, which can be configured individually via the WIKAsoft-TT PC configuration software. Measuring range, dampening, error signalling per NAMUR NE 043 and tag no. can be adjusted. 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. Through the compact design, this resistance thermometer is designed specifically for operation in applications with limited mounting space. Insertion length, process connection, sensor and connection method can each be selected for the respective application within the ordering information. The electrical connection is made via an M12 x 1 circular connector. For applications requiring the sterilisation of the instrument in autoclaves, an especially temperature-resistant instrument version is available.

Applications

Sanitary applications Food industry and beverage industry Pharmaceutical industry, production of active ingredients Biotechnology and Life-Science-Engineering Creamery, brewery

Special features

Compact design for space-saving fitting Simple and fast electrical connection via M12 x 1 plug connector With direct sensor output (Pt100/Pt1000 in 3 or 4-wire version) or integrated transmitter with 4 ... 20 mA output signal, individually parameterisable with free-of-charge WIKAsoft-TT PC configuration software Materials and surface finish quality in accordance with standards of hygienic design
