UV IR2 EXD HT Flame Detector

Product Overview

The flameproof Ultra-Violet, dual Infra-Red (UV/IR²) Flame Detector is designed to protect hazardous areas where open fires may be expected and detects almost all flames, including hydrocarbon fires with 4.3um emissions through to invisible fires such as hydrogen.

The UV/IR Flame Detector is sensitive to flickering, low frequency (1-15Hz) infra-red radiation emitted by flames during combustion. This detector has a UV sensor and two IR sensors which respond to different wavelengths of both the ultra-violet and the infra-red spectrum.

The signals from these sensors are processed by the detector and checked for characteristics of a flame. The simultaneous detection of both the UV and the IR light by the sensors will signal an alarm. False alarms from flickering sunlight, arc welding and lightning are eliminated by a combination of UV and dual IR signal processing techniques. The UV/IR2 detector has selectable output options of relay contacts or 4-20mA signal, as standard.
