The air purge unit complements the reliable CoolingJacket for use in harsh environments, especially in the metal and glass industries.
An integrated, infrared-transparent special window protects the optics of the camera or sensor on the one hand and enables an optimal laminar air flow on the other hand. This is particularly important because turbulence directly in front of the optics leads to dirt deposits. The Optris development engineers designed, extensively tested and optimized the air purge attachment in the in-house test center.
In harsh environments, the airflow in front of the CoolingJacket has proven to be as critical for reliable and accurate temperature measurements as the cooling itself. The air purge unit optimizes this airflow and allows both orthogonal (left) and parallel (right) airflow.
The universal protection housing (IP 66) has been developed for outdoor operation of the optris PI infrared camera series. Through a built-in air purge collar, the IR cameras can be deployed in dusty and humid conditions for a continuous temperature monitoring. The possible inclusion of a USB Server Gigabit enables for an integration into process control systems over large distances via Ethernet.
Interchangeable lenses are available for all optris PI infrared cameras. Additional lenses may also be purchased afterwards for every camera individually. The exact field of view for all thermal imagers at any distance can be calculated with our optics calculator. If you are uncertain which IR camera is the most suitable for your measuring task, use our IR camera selector!
