3.5 Temperature Range
The maximum permissible operating temperature of the indicator is: T6 = 70°C for Exd. 80°C for Exia.
T4 = 120°C for Exd, 125°C for Exia, 100°C for UL. If MFQ seals are used on the indicator, the lower temperature threshold
can be dropped to -40ºC. Surface temperature and/or general heat rise will mainly be generated by the fluid temperature
or ambient temperature, as the indicator itself produces minimal heat. Due to this the fluid temperature must not be
allowed to exceed these temperature ranges. T6 = 70°C for Exd, 80°C for Exia
T4 = 120°C for Exd, 125°C for Exia
100°C for UL
