QRB3火焰探测器

品牌：SIEMENS（西门子）

产地：德国

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.

此型号主要应用于意大利BALTUR百得燃油燃烧器上，大于30万大卡以上使用。
