Model 4000

The Model 4000 Strain Gauge is designed primarily for arc welding to steel structures such as tunnel linings, excavation bracing, piles and bridges. The standard gauge has a 150 mm gauge length (longer or shorter versions are also available), a 3000 µε range and a 1 µε sensitivity. Also available are the Model 4000-16 and 4000-17 extended range versions, which are designed for measuring large strains of up to 5,000 µε and 10,000 µε respectively. The gauge can be adapted for bonding to concrete or for bolting to steel surfaces by modification of the end blocks. The Model 4050 is a modified version of the Model 4000 that is designed for measuring strains over a longer base length.
