DANGER!
If you are unsure as to whether the device can withstand the loads of the process when using an
insertion-type thermometer without thermowell, have a separate strength calculation done (e.g.
per DITTRICH or MURDOCK, ASME PTC 10.9-TW)! For further information contact the
manufacturer.
INFORMATION!
The manufacturer can provide an optional strength calculation for a fee.
