Strain gauge for use in measurement sensor, has measuring grid located on carrier layer that is formed by metal foil, where metal foil is made of aluminum, copper, titanium or alloys such as steel, constantan and chrome or nickel alloys

摘要

The gauge has a measuring grid (3) that is located on a carrier layer (2), where the carrier layer is formed by a metal foil. The metal foil is made of aluminum, copper, titanium or alloys such as steel, constantan and chrome or nickel alloys. A sealing layer is provided for covering the measuring grid, where the sealing layer is formed by a foil made of an inorganic material such as glass or ceramic. An interconnection between the carrier layer and the measuring grid and/or between the measuring grid, the carrier layer and the sealing layer is produced by glue.
