QRB3 | 光敏電阻/火焰探測器 燃燒器專用【SIEMENS西門子LANDIS】 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. 網站標注價格為參考價，產品質量有保證，長年備有大量庫存現貨，隨時要貨，隨時發快遞。全國范圍內1-3天可以到達。 如需了解更詳細，請來電索取技術資料。 旺旺:wellpat 電話：0755 2767 5552，1367 002 1005,136 7000 7925 EMAIL:wellpat@139.com 主頁：http://wellpat.cn.alibaba.com
