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.
7.6.1 Operating limits for multipart, welded thermowells
TRA/TCA-TS32, -TF33 and -TS35 with Ø 12 x 2.5 mm / 0.47 x 0.10"
DANGER!
To prevent fatal injuries 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.
DANGER!
The information in this subsection is informative only and does not reflect the vibration load
caused by flow-induced eddy shedding and the resulting vibration. If necessary, prior to
purchasing and installing an industrial thermometerfor advanced requirements, have a specific
strength calculation performed (e. g. as per DITTRICH or MURDOCK, ASME PTC 19,3TW-2010).
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.
INFORMATION!
The thermowell operating limits specified below refer to a flow of air of 40 m/s or 131.2 ft/s or a
flow of water or vapour of 5 m/s or 16.4 ft/s.
