Arc Weldable (VW)
The Model 4000 Strain Gauge is designed primarily for arc welding to steel structures such as tunnel linings, excavation bracing, piles and bridges. The gauge has a 150 mm gauge length (longer or shorter versions are also available), a 3000 µε range and a 1 µε sensitivity. The gauge can be adapted for bonding to concrete or for bolting to steel surfaces by modification of the end blocks.
