Model KGN1
smoke sensor, mine-used Intrinsic Safety sensor, is
suitable for monitoring the fire event out of mechanical
friction, cable heating and coal layer in the coal mine
underground. It can be installed in the belt
transportation laneway, the electromechanical chamber, the
goaf and the working face.
Model KGN1 can be connected
with the power cuttingoff device and the acousto-opticl
alarm device to realize the alarm and the power cuttingoff
control. It can also be equipped with the production and
safety monitoring and control system. |
