Special features

    • Very compact design, high vibration resistance and fast response time
    • With direct sensor output (Pt100, Pt1000 in 2-, 3- or 4-wire) or integrated transmitter with output signal 4 ... 20 mA
    • Individually parameterisable for integrated transmitter with free PC configuration software WIKAsoft-TT
    • Sensor element with accuracy class A per IEC 60751


Resistance thermometers of this series are used as universal thermometers for the measurement of liquid and gaseous media in the range of -50 ... +250 °C [-58 ... +482 °F].

They can be used for pressures up to 140 bar with sensor diameter 3 mm and up to 270 bar with sensor diameter 6 mm, dependent on the instrument version. All electrical components are protected against humidity (IP67 or IP69K) and designed to withstand vibration (20 g, depending on the instrument version).

The resistance thermometer is available with direct sensor output or integrated transmitter, which can be configured individually via the PC configuration software WIKAsoft-TT. Measuring range, damping, fault signal per NAMUR NE43 and TAG no. can be adjusted.

Insertion length, process connection, sensor and connection method can each be selected for the respective application from the order information. The model TR33 resistance thermometer consists of a thermowell with 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, property right: 001370985).
