VW Spot Weldable Strain Gage

Overview

The Model 4100/4150 Strain Gage has a 51 mm gage length (3000 µε range, 1 µε sensitivity) and is designed to measure strains in steel structures (4100) and on reinforcement bars (4150) where space may be limited. The gage is installed quickly and easily by means of a capacitive discharge spot welder or, for short-term use, with special epoxy adhesives; the latter method of attachment permits the use of this gage on concrete.
