The main structure and working principle

 

 

System components

 

 

Color CCD camera system consists of industrial TV special lenses, monitors, electric tripod head(JMP), the controller, protective enclosures, cooling air hose, component video cables etc.

 

NDTV-2 drum water level television system component system

 

 

Principle

 

The connection system as shown in Figure 2, through the Industrial television images for the objective lens optical signal transmitted to the cameras, camera images of the optical signal into a video signal, and then by video cables to transmit video signals to a monitor display. The controller used to control the lens focal length, aperture, perspective and also about rotation can be controlled pan-tilt, swing from top to bottom.
