FBG Displacement Sensor DS- 01, DS-02
The DS-01 and DS-02 are designed to monitor the extension and compression displacement respectively. Double FBGs are packaged inside the housing. One FBG is used of its strain sensitivity to monitor the displacement. The second FBG is used as temperature compensation. The sliding rod can move freely over a customized distance from 10mm to 350mm.
