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
The model TR33 resistance thermometer is used as a general-
purpose thermometer for the measurement of temperatures from
-50 … +150 °C or -50 ... +302 °F (without neck tube) and -50 … +250 °C
or -50 ... +482 °F (with neck tube) in liquid and gaseous media. It can be
used for pressures up to 140 bar with 3 mm sensor diameters and up
to 270 bar with 6 mm sensor diameters, dependent on the instrument
version.
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.
If the instrument is transported from a cold into a warm environment, the
formation of condensation may result in instrument malfunction. Before
putting it back into operation, wait for the instrument temperature and the
room temperature to equalise.
