Magnet elongation is designed to measure settlement or heave of side soil protection walls, foundations, dams and soft ground.
Some magnets installed on a conduit get to have settled or hemmed up according to the up/down movement of a layer. When a probe in the direction of the pipe entering the magnetic field is carried out on the magnet, the switch is closed and the light and buzzer work. At this time, it can test the depth of the magnet. In particular, the signal tapes, which are made of steel, are coated so they are very strong and durable.
The system consists of a transducer, a reel frame, a signal tape, lights, a whistle, some spider magnets, and a conduit.
