Spesifikasi Photocell Siemens Type BIG Flange For QRB1
Photo Resistive Flame
Detectors
QRB1…
QRB3…
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.
