There are three types of flame detectors to be used depending on the light characteristics of the flame: one is a UV detector that is sensitive to the shorter wavelength UV radiation in the flame, and the other is an IR detector that is sensitive to the longer wavelength infrared radiation in the flame Detector; and the third is a hybrid UV / IR detector that detects both shorter and longer wavelengths of light in the flame.

Specific according to the detection band can be divided into: single UV, single infrared, dual infrared, triple infrared, infrared / ultraviolet, additional video flame detectors.

According to the type of explosion can be divided into: Flameproof, intrinsically safe.
