Infrared Flame Detectors
QRI...
Infrared flame detectors for use with Siemens burner controls, for the
supervision of gas, oil and other flames that emit infrared light.
The QRI... are suited for burners of any capacity, either in continuous or
intermittent operation.
The QRI... and this Data Sheet are intended for use by OEMs which integrate the
flame detectors in their products.
Use, features
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.
