|
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 burners of small capacity 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. This type of flame detector is suited for use with burner controls LOA2... (except LOA25...), LOA3..., LOA44..., LMOx4..., LGB3..., LAL1... and LAL4... and – in terms of plug-in facility – is compatible with the photoresistive detectors QRB1...
-
The spectral sensitivity of the QRC1... is a maximum of approximately 300 nm, which means that it optimally covers the range of UV radiation of blue-burning oil or gas flames. Since the QRC1... is also capable of detecting UV fractions of the radiation spectrum of other luminous sources (e.g. boiler house illumination or sunlight), the usual regulations for extraneous light still apply.
-
The QRC1... may not detect UV radiation of ignition sparks, as otherwise lockout will occur during the prepurge time, due to extraneous light. | |
