Three impulse control technology is widely used in industrial boiler control system. In the control of key parameters such as gas pressure, drum level and hearth negative pressure, drum water level is a top priority. High water level will lead to steam with water and produce capitation to the back of the equipment, which will seriously affect the normal operation of equipment. Low water level may cause dry boiler, which will make a destructive impact on equipment and even cause an accident. So accuracy measurement and control system for drum water level plays an important role in the safe production of boiler system.
Through the camera, Boiler drum water level industrial TV system can display two-color water level indicator on the monitor in control room. The industrial television system has clear and intuitive images. Compared with the traditional electric contact boiler water level monitoring device, it has high reliability, long service life, easy installation and convenient maintenance .
Boiler drum water level CCTV system consists lens, camera,electric PTZ or semi-fixed PTZ, air cooling camera housing, camera obscura (which will keep the camera a good view under harsh environment). The system offers compressed air cooling which cools this camera to work under 70 deg C temperature. According to users; needs, one TV or monitor can display 2 images, 4 images or 8 images.
