KFSB

Summary

The KFSB series foil strain gages are shielded by 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.

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

E.g.
For the gage with a low-noise vinyl-coated 3-wire cable 3 m long pre-attached
→ KFSB-5-120-J1-11 J3M3

If no lead-wire cable code is suffixed, the gage is delivered with 2 polyester-coated copper wires 25 mm long each.
