Shielded Foil Strain Gages
The KFSB series foil strain gages are shielded by the copper foil covering the whole body. Thus, if a large current flows to or around the gage bonding site, noise will be prevented from entering the measuring circuit.

Besides the polyester-coated copper lead wire, KFSB strain gages with pre-attached lead cables are available on request.
When ordering, suffix the lead-wire cable code to the model number with a space in between.
