Abstract
A precision force transducer having a spring element () whose load-dependent deflection is converted into an electrical signal by means of strain gauge elements (). The spring element () is made of a precipitation-hardenable nickel-based alloy with a nickel content in the range of 36 to 60 percent and a chromium content in the range of 15 to 25 percent. The strain gauge elements () are composed of a polymer-free layered film system. This makes it possible to produce a precision force transducer that features great accuracy, low creep and low moisture sensitivity.
