The TSD single-point settlement meter is composed of a displacement meter, an anchor head, a settlement flange plate, a measuring rod and other components. It is suitable for measuring the deformation and displacement of the soil between the anchor head and the settlement disk, and can be used for long-term monitoring and automated measurement. Its anchor head is set at the relatively fixed point (bedrock), the settlement disk is set at the monitoring elevation, and the conductor is led out from the side. When the foundation sinks, the settlement disk sinks synchronously with the foundation, causing the moving magnetic conductor of the sensor to slide relatively within its magnetic flux induction coil. The displacement is measured by a reading instrument to achieve the purpose of settlement observation and stratified settlement.
