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.

Key Features

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.

Compound Material Tensile Testing

NTB-500 Series devices can be used to connect strain gages directly, in order to measure high-elongation strain. In addition to measuring strain, voltage and temperature (thermocouple) can be measured using just a single device.

When ordering, suffix the lead-wire cable code to the model number with a space in between.
