Miniature resistance thermometer
Description
Resistance thermometers of these series are used as universal thermometers for the measurement of liquid and gaseous media in the range -50 ... +250 °C [-58 ... +482 °F].
They can be used for pressures up to 140 bar [2,030 psi] with 3 mm [0.12 in] protection tube diameters and up to 270 bar [3,916 psi] with 6 mm [0.24 in] protection tube diameters, depending on the instrument version. All electrical components are protected against humidity (IP67 or IP69K) and designed to withstand vibration (20 g, depending on instrument version).
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.

Insertion length, process connection, sensor and connection method can each be selected for the respective application within the ordering information. The model TR33 resistance thermometer consists of a protection tube with a fixed process connection and is screwed directly into the process. The electrical connection is made via an M12 x 1 circular connector. An adapter for electrical connection with angular connector per DIN EN 175301-803 is optionally available (patent, industrial property right: 001370985).
