2. Safety

WARNING!

Before installation, commissioning and operation, ensure that the appropriate thermo-

well has been selected in terms of measuring range, design and specic 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 specications contained in these operating instructions must be observed. Should

the thermowell be improperly handled or operated outside of its technical specications, 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 qualication

WARNING!

Risk of injury should qualication be insucient!

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 qualications 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-specic 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.
