QRB1 A-A 火焰探測(cè)器

顏色：黑色
Photoresistive flame detectors for use with Landis & Staefa burner controls, for the supervision of oil flames in the visible light spectrum. The flame detectors are used primarily in connection with burner controls for small burners.
-
With this type of flame supervision, the radiation of oil flames in the visible light spectrum is used for generating the flame signal.
-
The light-sensitive element is a photoresistor.
-
When there is no light, the detector′s resistance is in the MΩrange.
-
The resistance drops as the intensity of illumination increases (kΩrange).
-
In contrast to the selenium photocell of the RAR... detectors, glowing firebrick in the combustion chamber can be detected.
