Abstract
A strain gage includes, in stacked order, a backing film (1), a measuring resistor grid (2), and a cover (16) including a first layer (6) of an insulating material and a second layer (7) of a metallic material. At least the metallic second layer (7) of the cover is a metallic foil having a size or extension in the plane of the cover that is smaller than or equal to the size or extension of the backing film (1). The strain gage is simple to manufacture in a continuous strip or large sheet process, and is relatively insensitive to the effects of moisture or changes in humidity.
