PRECISION FORCE TRANSDUCER COMPRISING STRAIN GAUGE ELEMENTS

摘要

The sensor has a spring unit (1), whose load-dependent deflection by a strain measuring unit (10) is converted into an electrical signal. The spring unit consists of an exudation temperable nickel-base-alloy with nickel-content between 36 and 60 percent and chromium-content between 15 and 25 percent, where the strain measuring unit consists of a polymer-free coating system. An alloy with nickel-content between 50 and 55 percent and chromium-content between 17 and 21 percent is utilized as the nickel-base-alloy. Endpieces are made of plastic.
