Abstract


In the context of explosion protection of technological equipment in general and electrical equipment in particular, the paper estimates the uncertainty involved in measuring the maximum surface temperature for intrinsically safe and increased safety types of protection. Equivalent test scenarios have been considered, using different sensor application methods. The context of the work is presented in the first part. The second part presents the stand used for temperature tests and the theoretical model adopted for heat exchange. In the third part of the paper, the obtained results are presented and discussed. Based on the results, it is concluded that the uncertainty of temperature measurement is influenced by the test conditions and the way the temperature sensors are applied.
