2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate thermo-
well has been selected in terms of measuring range, design and specific measuring
conditions.
Before installation, commissioning and operation, ensure that the thermowell materi-
al used is chemically resistant/neutral to the medium being measured and that it
withstands the mechanical stresses from the process.
Non-observance can result in serious injury and/or damage to equipment.
Further important safety instructions can be found in the individual chapters of these
operating instructions.
2.1 Intended use
Thermowells are used to protect temperature sensors from the process conditions. Furthermo-
re, thermowells enable the removal of the temperature sensor without having to shut down the
process; and they guard against damage to either the environment or to personnel, which might
be caused by escaping process media.
The thermowell has been designed and built solely for the intended use described here, and may
only be used accordingly.
The technical specifications contained in these operating instructions must be observed. Should
the thermowell be improperly handled or operated outside of its technical specifications, it has to
be inspected immediately.
The manufacturer shall not be liable for claims of any type based on operation contrary to the
intended use.
2.2 Personnel qualification
WARNING!
Risk of injury should qualification be insufficient!
Improper handling can result in considerable injury and damage to equipment.
The activities described in these operating instructions may only be carried out by
skilled personnel who have the qualifications described below.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their technical training,
knowledge of measurement and control technology and on their experience and knowledge of
country-specific regulations, current standards and directives, are capable of carrying out the
work described and independently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive or toxic
media.
