IR FLAME DETECTOR QRI 2B2.B 180B

Key features of the QRI… flame detectors:

• 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. Owing to electronic self-supervision of the flame signal, the QRI… can be used in connection with suitable burner controls designed for burners in continuous or intermittent operation. The sensitivity of the QRI… is such that it must be fitted behind the burner’s baffle plate.
