Description
During tunnel construction, this sensor measures the displacement of the tunnel face ahead of the excavation at intervals of 1.0 to 3.0 meters.
By using high-resolution sensors, it provides highly accurate measurement results.

▣ Application
- Measurement of the advance displacement at the tunnel face during tunnel construction

Composition & Characteristics
▣ Product Composition
① Advance displacement sensor
② Connecting rod
③ Cable & accessories
▣ Features
① Each sensor cable is configured into a one-line connection, making installation simple and significantly reducing installation time.
② The one-line cable system also helps reduce installation costs.
