failure is not considered and is sufficient if the power passed
into the sensor does not exceed 0.05 W. Information about
maximum power passed into the sensor can be found in the
operating manual of the transmitter or associated apparatus.
8. During installation it should be taken into account, that the
equipment does not meet requirements EN 60079-11, strength
test 500 V

9. Maximal temperature of process (measured) medium for
explosion hazard environment of gases and temperature
classes are listed in the following table.

For process temperature (measured medium) 440 °C < Tm
≤ 1200 °C, the maximal surface temperature of sensor Tx
is determined from maximal temperature of the process
(measured medium) Tm and safety addition 10 °C.
Tx = Tm + 10°C
10. Maximal surface temperature Tx for dust explosive
atmosphere is equal to measured medium temperature Tm.
Tx = Tm
