燃燒器燃燒機(jī)電眼 火焰探測(cè)器 光電管BT-QRB1 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. 此型號(hào)廣泛應(yīng)用于各個(gè)品牌的燃油燃燒器上，包括德國(guó)WEISHAUPT威索、意大利BALTUR百得、意大利ECOFLAM意高、瑞典BENTONE百通以及大部分國(guó)內(nèi)品牌燃燒器。 網(wǎng)站標(biāo)注價(jià)格為參考價(jià)，產(chǎn)品質(zhì)量有保證，長(zhǎng)年備有大量庫(kù)存現(xiàn)貨，隨時(shí)要貨，隨時(shí)發(fā)快遞。全國(guó)范圍內(nèi)1-3天可以到達(dá)。 如需了解更詳細(xì)，請(qǐng)來(lái)電索取技術(shù)資料。
