8 MOUNTING/INSTALLATION
8.1 Safety
Thermowells must be used
for all processes and flowing
media subjected to pressure.
They protect the thermometer
stem against corrosion and
mechanical damage, and
permit the thermometer to be
removed without leaks.
8.2 Preparations
(requirements for the
installation location)
• A check on suitability of the
device and of the thermowell
that may be required for the
medium to be measured, the
arrangements in the scope
of measurement range and the extent of the protection
against special conditions such as vibrations.
• A bracket must be installed to support the gauge if the
metering pipe is not able to provide adequate support
• Devices with a blow-out require a minimum spacing to
the rear (20 mm).
• The operating temperature range is -30°C to + 80 °C.
8.3 Moutning/Intallation
• Using appropriate accessories, the device can be
installed on flat walls, mounting plates, on pipes or in
panels or boards.
• Ex works, the device is supplied and calibrated for
vertical installation.
• If the installation location deviates from the vertical (max.
± 5°), the zero setting on the indicator must be corrected
(see 7.4.1 Zero point adjustment).
