Underground Mine Use Optical Fiber Camera

Application

1.Suitable for coal mines containing explosive gas environments (methane, coal dust).
2.The altitude does not exceed 2000 meters, and the ambient pressure is (0.8~1.1)×105Pa.
3.Where there is no dripping or water intrusion, the ambient temperature is -5ºC~+40ºC.
4.The relative humidity of the surrounding air is not more than 95% (+25ºC).
5.Prevent water or other liquids from immersing inside the camera.
6.There is no gas that destroys metal and insulation in the surrounding medium.
