QRA50M是西门子火焰探测器的一种。Photo resistive detectors for use with Siemens burner controls, for the supervision
of oil flames in the visible light spectrum.
The QRB… are used primarily in connection with oil burner controls in intermittent
operation.
The QRB... and this Data Sheet are intended for use by OEMs which integrate the
flame detectors in their products.
Use
The QRB... are designed for the supervision of yellow-burning oil flames in connection
with burner controls type LAL..., LME7…, LMO..., LMV… and LOA…
They are suited for frontal or lateral (90°) illumination.
The maximum spectral sensitivity of the QRB… is about 600 nm, thus giving full consideration
to the maximum level of visible light radiation of yellow-burning oil flames.
Since the QRB… also acquires certain parts of the radiation spectrum of other light
sources (boiler room lighting, solar radiation, etc.), the standard regulations regarding
safety in connection with extraneous light still apply.上海众配热能设备有限公司*销售siemens火焰探测器
