Cảm biến đo biến dạng (Strain Gauges - Fiber Optic) Geokon FP4000
Overview
The Model FP4000 Fiber Optic Strain Gauges are designed for use in environments where it may be difficult to use conventional types of strain gauges because of space considerations, high levels of electrical interference or where intrinsic safety is an issue. Measurements of dynamic events are also possible with these gauges and the requisite dataloggers. The strain gauges have a very low coefficient of thermal expansion and can be used to measure both mechanical and thermo-mechanical strains in a variety of different materials.
