Strain Gages - Concrete Embedment Strain Gages

Concrete Embedment Strain Gages

The Model 4200(HT), 4202 and 4210 Vibrating Wire Embedment Strain Gages are designed for direct embedment in concrete. The Model 4200 (standard model) has a 153 mm gage length and is commonly used for strain measurements in foundations, piles, bridges, dams, containment vessels, tunnel liners, etc. The Model 4210 has a 250 mm gage length and is designed for use in mass concrete with coarse aggregates. It is extra rugged to resist bending, and has large flanges to provide greater engagement area. The 4202, with a 51 mm gage length, is designed for laboratory use and/or where there are space limitations.
