Guinea Bissau DQL100-G1 Mine Suspension Compass

The DQL100-G1 mine suspended compass and inclinometer are supplied as a set and serve as auxiliary surveying instruments for mining operations. The instrument is primarily used to measure the magnetic azimuth and the dip angle of compass traverse lines in secondary roadways and longwall faces within the mining area. The DQL100-G1 mine suspended compass consists of four main components: a bent-arm support assembly, a circular-ring frame assembly, a compass-box assembly, and a magnetic-needle assembly. The first three components together form a universal gimbal mount, which ensures that the compass box remains balanced in any orientation.
