KFRB Series Foil Strain Gages
The KFRB series foil strain gages/gauges are durable and easy-to-use polyimide high-grade strain gages. The gage/gauge element is sandwiched between heat-resistant polyimide base and cover, with NiCr alloy foil as its resistive element, thereby letting it exhibit high performance in a wide temperature range. It has self-temperature-compensation of 0 to 150ºC, applicable linear expansion coefficients (×10-6/℃) of 11,16 and 23. It is able to withstand strain limits of approximately 2.2(strain measurement at mid temperature, for transducers) at normal temperature and fatigue lives at normal temperature of up to 1x10^6 (±1500μm/m) (strain measurement at mid temperature, for transducers) times.
