8.8 Protective Window
The protective window can be used to protect the sensing head from dust and other contamination. This should be applied especially for sensors without a lens. These are all models with an optical resolution of 2:1.
The protective window is made from non‐poisonous zinc sulfide, with a transmission factor of 0.75 ± 0.05. It has an outer diameter of 17 mm (0.67 in). The protective window can be directly screwed to the sensing head. It withstands ambient temperatures up to 180°C (356°F).
For correct temperature readings, the transmission of the protective window must be set via the control panel in the sensor’s electronic housing, see section 6.2 Setting of Modes on page 35!
