KBA153 Mining intrinsically safe fiber optic cameraDetailed product description：

The KBA153 intrinsically safe fiber optic camera for mining is used in places with gas and coal dust explosion hazards underground in coal mines. This camera is a key equipment in the coal mine industrial television system for real-time image monitoring of major production processes, important equipment, and key positions. It can be transmitted using optical cables, coaxial cables, or twisted pair cables; Compact structure, small size, light weight, explosion-proof, earthquake resistant, moisture-proof, suitable for use underground in coal mines.
