3.1.3 Water cooled housing
To avoid condensation on the optics an air purge collar is recommended.
The sensing head is for application at ambient temperatures up to 85 °C. For applications at higher ambient
temperatures we recommend the usage of the optional water cooled housing (operating temperature up to
175 °C) and the optional high temperature cable (operating temperature up to 180 °C).

Water flow rate: approx. 3…5 l/ min
Water pressure: approx. 3…10 bar
(Cooling water temperature should not exceed 30 °C)
