7.6 Measuring range and permitted load
Temperatures that can be measured with an industrial thermometer depend largely on the load
of the thermometer. Load limits are defined through a variety of factors (see the subsection
"Load limits" in the "Installation" section). For this reason, the manufacturer cannot make any
universally valid statements about the measuring range and permissible load.
To prevent destruction or damage, never operate the thermometer outside of its permissible
mechanical, thermal or chemical limits. For further information refer to the rest of this section
and the "Technical Data" section.
Operating limits of thermowells with Ø 9 mm / 0.35"
CAUTION!
The information in this subsection is informative only and does not reflect the vibration load
caused by flow-induced vibration. If necessary, prior to purchasing and installing an industrial
thermometer, have a specific strength calculation performed (e. g. per DITTRICH or MURDOCK).
For further information contact the manufacturer.
CAUTION!
To prevent destruction or damage, only operate a thermometer without a thermowell in the
range of 0.8...1.2 bara / 11.6...17.4 psia.
INFORMATION!
The manufacturer can provide an optional strength calculation for a fee.
