Overview

Featuring a longer gage length, the KC series gages are wire strain gages suitable for mean strain measurement of concrete under test. Usually, a model with the gage length over 3 times longer than the maximum diameter of the aggregate (gravel, sand, etc.) is selected for the purpose.

Contents

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

For the gage with a vinyl-coated flat 2-wire cable 5 m long
→ KC-120-120-A1-11 L5M2R

If no lead-wire cable code is suffixed, the gage is delivered with gage leads only. (Silver-covered copper wires 30 mm long)
