WIKA TR21 Minitrans thermometer for sanitary applications

Click2Contact

The hygienic TR21 Minitrans, a compact resistance thermometer with integrated transmitter and with a diameter of 19 mm, enables space-saving installation, whether directly or within a thermowell.

The thermometer operates in the range between -50 and +150°C and the span can be increased to +200°C using an optional neck tube. The electrical connection is simple to make via an M12 connector, with the measured value transmission via a 4-20 mA output. The measured value can also be taken directly from the sensor (Pt100 Class A) for more space saving.

For direct installation, the thermometer is available with all established process connections. In combination with model TW22 or TW61 thermowells the instrument can be calibrated or exchanged without opening the process. Any possible contamination is therefore prevented. For hygienic design, WIKA follows the requirements of EHEDG and the 3-A Sanitary Standards.
