KFSB Series Shielded Foil Strain Gages
The KFSB Series Shielded Foil Strain Gages/Gauges are shielded by the copper foil covering the whole body. Thus, if a large current flows to or around the gage bonding site, noise will be prevented from entering the measuring circuit. They are made up of polyimide with resistive element made of 120 Ω CuNi alloy foil and 350 Ω NiCr alloy foil. They have self-temperature-compensation of 10 to 100ºC and an applicable linear expansion coefficients (×10-6/℃) of 11,16 and 23. They are able to withstand strain limits of approximately 0.5% at normal temperature and fatigue lives at normal temperature of up to 1x10^4 (±1500μm/m) times.
