Product introduction

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 capac ity 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 degrees) 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.
