2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate thermo-
meter has been selected in terms of measuring range, design and specic measuring
conditions.
Choose the thermowell with regard to the maximum pressure and temperature (e.g.
rating chart in DIN 43772).
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
These resistance thermometers and thermocouples are used for temperature measurement in
industrial applications, in hazardous areas.
Resistance thermometers are used for measuring temperatures from -200 ... +600 °C. For
thermocouples, the possible measuring ranges range from -200 ... +1200 °C. Thermometers
of this design can be installed directly in the process as well as in thermowells. The thermowell
designs can be selected as desired, but the operating process data (temperature, pressure,
density and ow rate) must be taken into account.
