LumEx® Optical Detector

The LumEx® optical detector is an infrared detector designed for detecting explosions or flame propagations. LumEx® detectors are often used for detection purposes on isolation applications and bucket elevator suppression solutions. The detector features two silicon photodiodes that are looking for high saturation of UV/IR radiation, indicative of flame propagation. These diodes are less sensitive to light sources compared to traditional optical detectors which limit false readings.

Each LumEx® detector is provided with a welding adaptor that includes an air sweep connection. The air sweep connection is meant to keeps the lens clear of particulates, and the detector has an internal self-checking function to alarm when cleaning is needed. LumEx® detectors also have the ability to record a data log of events including activations and faults.
