KFS Series
Shielded Foil Strain Gages

Summary

The KFS 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 is prevented from entering the measuring circuit.

Contents

Besides the polyester-coated copper lead wire, KFN 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.

e.g.
KFS-5-120-J1-11 suffixes J3M3 for the gage with a 3 m long low-noise vinyl-coated 3-wire cable becomes
KFS-5-120-J1-11 J3M3
