SIEMENS RAR9 photo cell detector (pengganti rar7) – Flame Detector / Sensor / Sensor Api / Flame Sensor

SIEMENS RAR9

The photocell detectors are designed for use with burner controls, for the supervision
of yellow-flame oil flames.
They are used especially in connection with burner controls for the control and
supervision of large-capacity burners.
The RAR… and this Data Sheet are intended for use by OEMs which integrate the
flame detectors in their products!

The RAR… flame detectors are used for the supervision of yellow-burning oil flames.
They are designed for use with the following types of burner controls: LAL…, LAE1…,
LOK16… and LAE10…

Function
With this type of flame supervision, the radiation of oil flames in the visible band of the
light spectrum is used for generating the flame signal.
The light-sensitive element is a photocell. When illuminated, it generates DC voltage,
causing a current to flow to the input of the flame signal amplifier. Hence, the RAR… is
an active detector.
The photocell is insensitive to infrared radiation so that glowing firebrick in the combustion
chamber cannot produce a flame signal.
