2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate
resistance thermometer has been selected in terms of measuring range,
design, specific measuring conditions and appropriate wetted parts' materials
(corrosion).
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
Model TR30 and TR31 resistance thermometers are used as general-purpose thermometers
for the measurement of temperatures from -50 … +150 °C (without neck tube) and
-50 … +250 °C (with neck tube) in liquid and gaseous media. They can be used for pressures
up to 40 bar (special designs to 400 bar dependent on insertion length and diameter).
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.
