Thermal Imaging Cameras Offer Economical Solutions for a Variety of Diagnostic Applications
With the introduction of a new generation of cheap cameras, infrared cameras, thermal imaging technology which is now an effective problem solving, analysis and preventive maintenance tool for a variety of applications. Infrared cameras are lightweight, ergonomic, intuitive and contain high resolution thermal detectors that offer valuable temperature information to identify problems. This article gives an explanation of the technologies and applications where it is well suited.
Infrared cameras work just like digital cameras, except that they include a thermal image. The detectors measure infrared radiation, which is then converted into electrical signals, to add create a visual representation of the heat of an object. The visual representation shows the cool items in various shades of blue and hot lines in different shades of red and can be analyzed and formatted on a computer with a USB download. When deciding on a thermal camera, the most important functions is to take into account the resolution, accuracy and temperature range. The resolution in pixels. Each pixel on the screen is a discrete temperature, the more pixels the camera, the more detailed thermal image. The accuracy is measured as a percentage of the value of reading. Most cameras have accuracy of 2-5%. Finally, the infrared cameras is limited to a certain temperature range. If your application is dealt with extreme heat or cold, make sure the camera is in these measurements.
While the general specifications are similar from one camera to another, high-end cameras offer additional features that you may find useful. Many cameras offer photographic overlays of the thermal image. This is for the identification of components of the ideal and their proximity to each other in the thermal image. Cameras for monitoring of construction and plumbing industry offers dewpoint and insulation alarms useful in locating areas of moisture or insufficient insulation. Some cameras have documented even voice annotation and flashlights to illuminate dark areas.
There are many applications for infrared cameras, which before the introduction of cheap deals that were previously inhibitory costs. The heat signature of electrical circuits and components, machinery, can trigger further problems and failures. HVAC systems and thermal visualization of structures show obvious deficiencies, inadequate insulation, moisture and loose fitting channel. Pest control experts can detect infestations within the walls or enclosed spaces, as a result of breeding sites is ad higher temperatures than the surrounding areas. Professional plumbers to find blockages in pipes and law enforcement agencies may help in the search for hidden suspects. Even paranormal investigators found cameras, infrared cameras, a consultant in their discovery.
Infrared cameras cost as little as $ 3000 from manufacturers such as Extech, FLIR and Fluke, so that an economic analysis and diagnostic tools for a variety of professions. Many may not consider thermography as a good preventative maintenance or diagnostic solution to preconceived ideas about it, or a lack of knowledge about thermography applications. But combined they have invested in technology, a way to differentiate their business from competitors and to reduce the burden of “old school” methods that exist.
