WARNING!
Avoid putting mechanical stress on the electrical connections
or on the enclosures. The maximum temperatures of
-50… +150 °C (without neck tube) and -50 … +250 °C or
-50 ... +200 °C for TR30-V (with neck tube) must not be
exceeded. Connections must only be opened when the
instrument is depressurised and has cooled down.
6.1 Mounting
These resistance thermometers are designed for screw-fitting directly
into the process. The insertion length, along with the flow velocity and
viscosity of the process media, may reduce the max. loading on the
thermowell.
Installation examples
For information on tapped
holes, please refer to DIN 3852,
or for NPT threads ANSI B 1.20.
