Technical Information
Protective Cooling Jacket
The HEITRONICS Infrared Radiation Thermometers can be operated at an environmental
temperature of up to 60 °C/ 70 °C
1
without any additional coolants. If the environmental
temperatures are higher than that mentioned above, cooling fittings can be used.
Basically, the protective cooling jacket can be cooled with air or water. The possible
maximum environmental temperatures are higher for water cooling than for air cooling
(
individual data sheets).
If the cooling process is too strong, i.e. if the cooling air / cooling water is too cold, this
may result in condensate at the protective cooling jacket as soon as cooling medium
falls below the dew point. To prevent this from occurring, the cooling air / cooling water
must have a minimum temperature as a function of the relative humidity.
The following table specifies the minimum temperature of the cooling air / cooling water
as a function of the environmental temperature and the relative humidity of the environ-
mental air.
