WARNING!

Before installation, commissioning and operation, ensure

that the appropriate resistance thermometer has been

selected in terms of measuring range, design, specic

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 TR31 resistance thermometer is used as a general-

purpose thermometer for the measurement of temperatures from

-50 … +150 °C or -58 ... +302 °F (without neck tube) and -50 … +250 °C

or -58 ... +482 °F (with neck tube) in liquid and gaseous media. The

version with mineral-insulated sheathed cable and neck tube allows

to measure temperatures up to 300 °C or 572 °F. 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 specications contained in these operating instructions

must be observed. Improper handling or operation of the instrument

outside of its technical specications 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
