JAB-IIIC type of security alarms, heating furnace for oil pipelines, recycled water and general heating fuel (gas) boiler and other safety automatic monitoring, alarm and control. The instrument is based on a variety of furnace, boiler different forms, using three methods to monitor the flame (a) UV-sensitive tube: According to the burning flame spectral characteristics of inflammatory mediators, the UV sensitivity, good linear small dark current and circuit control and high stability and other characteristics, widely used set of UV monitoring: (b) of the probe type: According to the principle of ionic conductivity, flame monitoring device for: (c) of the screen display style: the use of modern means the flame tracking camera, and then transmitted to the color signals to the display, very intuitive apparent flame combustion, the flame not only improve the monitoring means, but also improve the visual monitoring of the flame and safety and reliability. The instrument can be heated with a medium to measure the temperature and pressure, so that officers on duty in the room that is easily audible and visual alarm, indicating an immediate duty to take safety measures. There is a table placed in the instrument type, wall-mounted and panel-mounted, can be arbitrarily selected according to different needs.
