3.2 Intended use

The model TR21 resistance thermometer has been specifically designed for the
measurement of temperatures in vessels or pipes, in the range of -30 ... +150 °C
[-22 ... +302 °F] or -30 ... +250 °C [-22 ... +482 °F], which are used in sanitary applications.
Here, the protection tube is used to protect the temperature sensor from the process
conditions. Furthermore, the detachable connection from the protection tube in the TR21-A
and TR21-B variants enables the removal of the temperature sensor without having to shut
down the process; and thus guards against any damage to the environment or to personnel
which might be caused by escaping process media.
