2.3.1 Compact versions
• The OPTIFLUX 6300 C is suitable for an ambient temperature range of -40...+60°C.
• The minimum process temperature is -40°C.
• For dust hazardous areas the maximum surface temperature is 150°C at an ambient
temperature T
a
≤ 60°C.
• The maximum process temperature T
p
depends on the required temperature class T6...T3
and the maximum ambient temperature T
