Summary of Contents for QRI Series

Page 1: ... Detector with infrared sensitive flame detecting element Integrated flame signal amplifier Designed for frontal and lateral 90 illumination Suited for use with burner controls type LMV5 Secured to the burner with flange and clamp The spectral sensitivity of the QRI is a maximum of about 2 µm covering infrared radiation emitted by gas oil and coal flames as well as other sources of infrared light ...

Page 2: ...ence or similar may modulate infrared radiation emitted by hot boiler or burner components in a way that a flame will be simulated Likewise moving parts in the detector s viewing range can cause infrared radiation from the boiler or a viewing tube to be modulated thereby possibly generating sporadic detector signals Strong burner or detector vibrations can also produce variations in radiation For ...
