R4348 A/1026 This Monitor is non-contact and the sensitive element is a UV photocell, which is placed away from the flame but “in sight” of the flame. The ultraviolet photosensitive tube is a special light-sensitive element, which receives ultraviolet light of 180-260 mm wavelength from the flame, while x is insensitive to light from the sun, incandescent lamps, fluorescent lamps, incandescent parts, etc. It has high sensitivity and impact. It has a high sensitivity, fast impact speed, anti-interference ability and so on.
