Flame detector selection: Part 1 - detection technologies

摘要

This article has provided some pointers for the selection of flame detectors based on the technologies employed and application. Today most flame detectors sold are either UV-IR or IR3 based. Devices using these technologies can detect a wide range of fire types, with the performance mainly being determined by the IR wavelength selected. The detectors are extremely immune to false alarms, but significant differences in performance exists from vendor to vendor, particularly for IR3-based detectors. In part two we will discuss application and design considerations for your flame-detection system in greater depth.
