4600 Ember Detector (obsolete)
The ODTI 4600 Infra Red Ember Detector is an ultra sensitive optical sensor designed to detect the radiant energy emitted by burning or glowing embers being transmitted on conveyer belts. The detector is designed to detect a 1 sq. inch ember at a distance of 3 feet traveling at up to 20 fps.
The 4600 is sensitive only to the radiation emitted by the formation of CO2 produced by a smoldering ember and is insensitive to ambient light - even solar.
