Not a job to be accomplished on foot. Therefore, an infrared camera of the VarioCAM® HDx research 600 series is mounted on the roof rack of a car with a pan/tilt head. Its robust light metal housing, combined with the LEMO® plug connections that maintain the degree of protection, ensures that the system is not affected by any weather conditions. The custom-built design includes a cable entry into the vehicle interior. Here, Peter Becker and his colleagues can monitor and evaluate the recordings live on the monitor of their notebooks. „Wherever a leak has formed, even small temperature differences can be clearly seen on the road surface. In this way, we can inspect a large area of the district heating network within a short period of time," explains Peter Becker. The consumer will not notice any of this. The monitoring is basically carried out during regular network operation and proves to be extremely accurate.
Thermal images can be viewed and evaluated live while driving, for example to inspect joints. The excellent technical characteristics of this thermographic camera enable reliable leakage location instantly even if leaks are only distinguished from the environment by small temperature gradients. The road to success: Its high-quality microbolometer detector in the format (640 × 480) IR pixels and the capability to detect smallest thermal differences up to 30 mK.
Special construction with pan-tilt head on the roof rack.
Since 2017, Netze Duisburg GmbH has been using an utility vehicle equipped with an infrared camera.
