7.3.2 Air Purge Collar (A-TV-AP)
The Air Purge Collar (A-TV-AP) is used to keep dust, moisture, airborne particles, and vapors away from the lens.
Air flows into the 1/8” NPT fitting and out the front aperture. Clean filtered (or “instrument”) air is recommended to
avoid contaminants from settling on the lens. Do not use chilled air below 10°C (50°F).
Air flow rate:
30 to 60 l / min (8 to 16 gallon / minute)
Air pressure:
max. 5 bar (72.5 psi)
Note
To avoid erroneous readings, ensure that the transmission of 0.94 for the built-in protective window
(Germanium) must be set in the thermal imager!
