KFU Series High-temperature Foil Strain Gages (350ºC)
The KFU Series High-temperature Foil Strain-Gage/Gauge base is made of highly heat-resistant polyimide and the gage element is made of NiCr alloy foil, thereby letting the KFU series gage exhibit superior characteristics over a wide temperature range. It has a self-temperature-compensation of 10 to 300ºC, applicable linear expansion coefficients (×10-6/℃) of 11,16 and 23. It is able to withstand strain limits of approximately 1.9% at normal temperature and a fatigue lives at normal temperature up to 1.5x10^5 (±1000μm/m, 300ºC) times. Please use KFU for short period testing. E.g. 72 hours or less at 350 °C, 360 hours or less at 300 °C, adhesive PI-32 (It changes depending on the condition.)
