Infrared Temperature Sensors

Infrared Temperature Sensors detect electromagnetic waves ranging from 700 nm to 14,000 nm. These sensors function by focussing the infrared radiation of the object onto one or even more photodetectors. These photodetectors turn that energy into an electrical signal that is proportionate to the infrared energy of the object. Because emitted infrared radiation of each item is proportionate to its temperature, the electrical signal offers an exact readout of the temperature of the item at which it is aimed. In addition, the infrared impulses enter the sensor via a window constructed of a specific plastic.
