3 Overview

The top plate dynamic meter is a measuring instrument that measures the displacement of the top and bottom of the rock. According to the structure type points For the pointer roof dynamic instrument and digital top panel dynamic instrument. Pointer-type roof dynamic instrument is through the rack and gear drive, The linear displacement of the measuring rod is converted into the angular displacement of the pointer, and the measured value is indicated by the dial scale. The displacement sensor and the processing display part convert the linear displacement of the spindle into a digital display. Common structure shown in Figure 1, figure 2. Figure 1 pointer roof dynamic instrument 1-cm scale; 2-mm scale; 3-gauge pointer; 4-dial; 5-pointer; 6 - clamping sleeve; 7 - measuring rod; 8 - measuring head; 9 - supporting claw Figure 2 Digital topboard dynamic instrument 1-case body; 2-function key; 3-display; 4-mount sleeve; 5-measuring rod; 6-probe;
