KFNB Series
Non-inductive Foil Strain Gages

  • RoHS

KFNB

Summary

The gage element is made of a special alloy which provides less magnetoresistant effect; also, the shape is designed to eliminate induction. Thus, the KFNB series foil strain gages can accurately measure strain under AC magnetic environments.

Contents

Besides the silver-covered copper lead wire, KFNB 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.

E.g.
For the gage with a low-noise vinyl-coated 3-wire cable 5 m long pre-attached
