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.
High or very low temperatures, humidity and dust - such environmental conditions pose great challenges for electronics. In order to be able to use sensitive devices without problems, protective measures are usually necessary. In order to be able to use the infrared cameras of the PI and Xi series, for example, even under adverse conditions, Optris now offers a new outdoor housing that ensures optimum protec-tion for the sensitive devices. The new housing offers for the first time the possibility to integrate an infrared camera and an HD video camera together in one compact system. A compact USB server is also integrated in the housing.
The new housing complies with protection class IP66 and can therefore also be used in dusty or humid environments without any problems. In order to be able to use the infrared camera even at very low temperatures, an electrical heating element is included that switches on automatically at temperatures below +15 °C. A ventilati-on fan distributes the warm air evenly within the housing. This means that the sys-tem can also be used at temperatures as low as -40 °C. In warmer areas of use, tem-peratures up to +50 °C are possible. The optionally available air purge unit, which continuously purges the protective window of the housing with compressed air, ensures that no dust or condensing moisture can collect there. The infrared camera thus always has optimum visibility and can measure temperatures reliably.
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!
The following lenses are available for the thermal imagers of the optris PI series:
