High-elongation Foil Strain Gages
Developed to measure strain in elastic to plastic region on structures, the KFEL series foil gages can measure strain as large as 10% to 15% with simple tension strain.
|Materials Resistive element||CuNi alloy foil|
|Operating temperature in combination with major adhesives after curing (°C)||CC-36: -10 to 80ºC|
|Operating temperature in combination with major leadwire cables (°C)||Polyester-coated copper cable: -10 to 80ºC
Vinyl-coated flat cable(L-6, L-7): -10 to 80ºC
|Applicable linear expansion coefficients (×10-6/℃)||-|
|Strain limits at normal temp. (approx. %)||15.0|
|Fatigue lives at normal temp. (times)||1x106 (±1000μm/m)|
Besides the silver-clad copper lead wire, KFEL strain gages with pre-attached lead cables are available on request.
When ordering, please suffix the lead-wire cable code to the model number with a space in between.
KFEL-5-120-C1 suffixes L3M2R for the gage with a 3 m long vinyl-coated flat 2-wire cable becomes
