As well as replacing individual components, it is also possible to replace the entire
thermometer, however you as operator have sole responsibility for this:
DANGER!
In order to prevent injury or material damage when replacing components of the industrial
thermometer, always observe the following points:
• Before dismantling the electrical connecting lines of the device, ensure that all the cables
leading to the measuring insert are de-energised themselves and to the reference potential
of the explosive area. This also applies to equipotential bonding conductors (PA).
• All the relevant process controls or containers must be depressurized before dismantling the
thermowell.
• If the process cables or the container contain products that are harmful to the environment
or to health, implement the appropriate safety measures before dismantling the thermowell.
• Replace all the seals when reinstalling the device in the process cable or container.
