| Abstract: |
| The NDCY 1 electrical horizontal displacement gauge is developed based on the previous one with mechanical tension wire. The gauge can be embedded segmentally or wholly at one time for observation. The results of laboratory calibration test show that its accuracy of measurement is high; its structure is firm and stable; and its adaptability is ideal. |
