Infrared Flame Detectors
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.
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.

Page 2: Warning Notes
Warning notes To avoid injury to persons, damage to property or the environment, the following warning notes must be observed! Do not open, interfere with or modify the flame detector! · All activities (mounting, installation and service work etc.) must be performed by qualified staff. -
Page 3: Installation Notes
Installation notes Locate the detector such that, if possible, only the flickering peripheral range of the flame will be detected. The view at hot boiler walls or other hot boiler or burner components must be restricted as much as possible. This can be attained by clearly confined viewing conditions behind narrow baffle plates. - Page 4 ISO 14001:2015 OHSAS 18001:2007 China RoHS Hazardous substances table: http://www.siemens.com/download?A6V10883536 For use in the U.S. / Canada, the flame detectors carry the marks. Service notes To clean the detector’s lens, use a soft, clean cloth (free from oil and solvents).
