Settlement and Displacement
Magnetic settlement meter
Settlement measurements in embankments.
The magnetic setter ST110 has been designed to be installed in drilling holes, allowing to detect vertical displacements between various shares in the ground. It consists of a double guide tube, (a corrugated tube on the outside and a PVC tube on the inside) around which self-anchoring magnetic rings are arranged at predetermined heights covered in plastic material.
The settling column is formed in the borehole and/or as the embankment is built. At the bottom of the hole is a telescopic anchor equipped with a reference ring, while at the top, a suspension head.
The measurement is performed by lowering the settling probe inside the tube, which will indicate the various magnetic rings placed at a height, considering the top of the tube as a reference for the measure. By measuring the distance between the reference points and the head of the column, the absolute settlements of the ground are obtained.
The bedding probe is portable, compact and light. It consists of a PVC roller inside which there is a centimeter or millimeter rib, of variable length. At the end of the rib there is the measurement sensor (tip), which, by intercepting the magnetic ring, closes an electrical circuit housed inside the roller. The contact detection devices contained in the central body of the roller consist of optical-acoustic indicators powered by a 9V battery.
When ordering, you can request the COMBO tip in order to have 2 instruments in 1: the settling probe and the level probe (water level meter).
