Ultrahigh-elongation Foil Strain Gages
KFEM series ultrahigh-elongation foil gages allow strain to be measured on various regions of structures, from elastic to plastic, and are suitable for large strain measurement.
They can measure 20 to 30% of material deformation.
*Strain limit of 20% to 30% is ensured for simple tension applied to the gage bonded on stainless steel (SUS 304) or aluminum alloy (A1050) at normal temperature.
• Measurement of 20% to 30% material deformation possible
• Laminate protruding from the tip of gage base ensures improved adhesive property, making the gages hard to peel off.
• Foil material has an improved elongation property and is hard to disconnect.
|Materials Resistive element||CuNi alloy foil|
|Operating temperature in combination with major adhesives after curing (°C)||CC-36: -20 to 80ºC|
|Operating temperature in combination with major leadwire cables (°C)||Polyester-coated copper wire: -20 to 80ºC
Vinyl-coated flat cable (L-6, L-7): -10 to 80ºC
|Applicable linear expansion coefficients (×10-6/℃)||ー|
|Strain limits at normal temp. (approx. %)||20 to 30|
|Fatigue lives at normal temp. (times)||ー|
When ordering, suffix the lead-wire cable code to the model number with a space in between.
For the gage with a vinyl-coated ﬂat 2-wire cable 10 m long pre-attached
→ KFEM-5-120-C1 L10M2R
If no lead-wire cable code is suffixed, the gage is delivered with gage leads only.
(Silver-covered copper wires 25 mm long)
