Strain Gauge: Working Principle and Type
Thu, Feb 2, 2023
The box-type resistance strain gauge is a sensitive element based on the strain-resistance effect, using metal foil as a sensitive grid, which can convert the strain of the tested piece into the resistance change. There are many types of strain gauges. A general strain gauge is a plastic film (15-16μm) called the base. A sensitive grid (3-6μm) made of a thin metal foil is pasted, and then a layer of film is covered to form a laminated structure.
