WARNING!
Before installation, commissioning and operation, ensure that the appropriate
thermometer has been selected in terms of design and specific measuring conditions.
Before installation, commissioning and operation, ensure that the thermowell material
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 the equipment.
Further important safety instructions can be found in the individual chapters of these
operating instructions.
2.1 Intended use
Resistance thermometers for temperature measurement in processes with extremely high
hygienic requirements, in hazardous areas. These thermometers are used in applications where
a thermowell immersed into the process medium is not possible or not desired.
The instrument 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.
Improper handling or operation of the instrument outside of its technical specifications requires
the instrument to be taken out of service immediately and inspected by an authorised WIKA
service engineer.
