A GTF 101-Ex or GTF 102-Ex complying with the protection class EEx em II T6 or EEx ia IIC T6
can be used, if the temperature has to be detected in EX-zone 1, 2 or 21, 22. In case the

complying with the demands of the certain zone are allowed to be used.
In case the controlling- or displaying device is beyond the explosion hazardous area, this device
does not need an Ex-certification if a temperature-probe GTF 101-Ex or GTF 102-Ex complying
with the protection class increased safety (EEx em II T6) is used and the safety instructions given
in chapter 2 are fulfilled.
