Store the instrument in its original packaging in a location that fulfils the conditions listed
above. If the original packaging is not available, pack and store the instrument as described
below:
1. Wrap the instrument in an antistatic plastic film.
2. Place the instrument, along with shock-absorbent material, in the packaging.
3. If stored for a prolonged period of time (more than 30 days), place a bag containing a
desiccant inside the packaging.
WARNING!
Before storing the instrument (following operation), remove any residual
media. This is of particular importance if the medium is hazardous to health,
e.g. caustic, toxic, carcinogenic, radioactive, etc.
6. Commissioning, operation
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 (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.
