Geokon Vibrating Wire Surface Mount Strain Gauge
Product Information
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.
Spot weldable gauge is also available https://www.geokon.com/4100-4150.
