QRC УФ датчик пламени для контроля голубого или желтого пламени.
Blue-flame detectors for the supervision of blue- or yellow-burning oil or gas
flames. Blue-flame detectors are used primarily in connection with burner controls for
small-capacity burners in intermittent operation.
The QRC1... is a compact UV-sensitive blue-flame detector with an integrated preamplifier.
It is designed for frontal and lateral (90°) illumination.
QRC1... is suited for use with following burner controls and with photoresistive detectors
QRB1... - in terms of plug-in facility:
- LOA2... (except LOA25...), LOA3...
- LMOx4...
- LGB3...
- LAL1...
- LME23…
- LMV2…, LMV3...
The spectral sensitivity of the QRC1... is a maximum of approximately 300 nm so that it
optimally covers the range of UV radiation of blue-burning oil or gas flames.
Since the QRC1... also detects UV fractions of the radiation spectrum of other luminous
sources (e.g. from boiler house illumination or sunlight), the standard regulations for
extraneous light still apply.
The QRC1... must not detect UV radiation from ignition sparks, as otherwise lockout
occurs during the prepurge time, due to extraneous light.
