CAUTION!
EN Before installing, commissioning and operation,
ensure that the appropriate bimetal thermometer has
been selected in terms of measuring range, design and
specific measuring conditions. The compatibility of the
wetted parts of the process connection (thermowell,
thermowell stem) with the medium must be tested.
Non-observance can result in serious injury and/or
damage to property.
Further important safety instructions can be found in the
individual chapters of these operating instructions.
2.1 Intended use
