Foil Strain Gages for Plastics
The KFP series foil strain gages provide an applicable linear expansion coefficient of 65 x 10 –6 /ºC, which makes them suitable for strain measurement of plastics such as acrylic resin.

Besides the silver-clad copper lead wire, KFP 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.
KFP-5-120-C1-65 suffixes N10C3 for the gage with a 10 cm long polyester-coated copper 3-wire cable becomes

To Ensure Safe Usage
*When bonding the KFP gage to difficult-to-bond material such as polyethylene with CC-33A, use Surface Treatment Agent S-9B in combination.
