Can the sticker malfunction?
Activation of the sticker is based upon a simple principle: the substance melts at certain high temperature. It is identical to snow melting. When the pavement is covered with snow it's white. Once the sun comes out the snow melts and the pavement turns black. The temperature drops below zero but still the pavement remains black. For the pavement to turn white again the snow should fall. In our case it means that you are supposed to place a new sticker.
Why do I need such sticker if I have a thermal imager?
A thermal imager gives information only about current temperatures. Overheating occurs because of operating at full capacity.

In addition, the sticker is always visible, so the problem could be detected by any worker.
