Designed with ultraviolet (UV), UV/infrared (UV/IR) and multi-spectral IR (MSIR) sensing technologies, our Flame Detectors represent the state-of-the-art in flame monitoring. They feature advanced microprocessors, with neural network intelligence available on some models, along with continuous optical path monitoring (COPM), digital frequency analysis (DFA) and flicker discrimination circuitry. They provide the highest levels of protection available with superior false alarm immunity and excellent field-of-view capability. To support applications worldwide, they feature universal approvals: CSA, FM, ATEX, IECEx and/or CE Marking approved.
