There are a number of components that contribute to each the quality and the price of a thermal imaging camera. The 2 most vital factors are the detector resolution and the thermal sensitivity.
Thermal sensitivity is the smallest temperature distinction the camera can detect. A sensitivity of 0.05° means the camera can distinguish between two surfaces with solely a 5-hundredths of a degree temperature difference.
One other vital factor to consider is the thermal imaging camera’s temperature range. The range tells what the minimum and most temperatures are that the camera can measure (-4°F to 2200°F is typical).
To acquire the most effective thermal image to investigate, there are 4 adjustments that can be made to most cameras: focus, emissivity setting adjustments, reflective temperature setting modifications and thermal tuning. Each of these adjustments should be considered when selecting a thermal imaging camera.
Just like an ordinary camera, the lens of the thermal imaging camera must be focused to boost the readability of the image. Most cameras can be focused by twisting the lens. More sophisticated cameras have a push-button focus.
Emissivity is the amount of radiation emitted from an object compared to that of an ideal emitter of radiation when each are on the identical temperature. Adjusting the emissivity is necessary when taking temperature measurements or when comparing the temperatures of two different objects. Not all cameras enable the user to enter reflective temperature.
The reflective temperature setting permits the consumer to compensate for surrounding objects’ temperature reflecting on an object. Just like emissivity, reflective temperature is essential when taking temperature measurements or comparing two objects’ temperatures. Not all cameras permit the user to input reflective temperature.
Thermal tuning the camera involves adjusting the span or temperature range that the camera sees while in manual viewing mode. Manual mode permits the consumer to adjust the span to a desired range, and the camera will all the time display this temperature range. Utilizing the handbook mode is finest when used to deliver out temperature variations of the item being viewed.
Thermal Imaging Camera Limitations
Because thermal energy can be reflected off shiny surfaces, thermal imaging cameras can’t see through glass. Thermal imaging cameras can be utilized to collect information about the inside of a wall, however they can not see through walls. It’s also important to know that thermal imaging cameras shouldn’t be used as the only deciding factor that a problem exists. Using different devices should all the time be used to substantiate the problem.See More
