Vibrating Wire Surface Strain Gauge
BGK4000/4000HP Vibrating Wire Surface Strain Gauge is primarily used for monitoring strain on steel structures such as pipelines and steel sheet piles, as well as surface strain on concrete structures like bridges.
BGK4000/4000HP Vibrating Wire Surface Strain Gauge is primarily used for monitoring strain on steel structures such as pipelines and steel sheet piles, as well as surface strain on concrete structures like bridges. The two end blocks of the instrument can be either arc-welded or bolted onto the surface of the structure to monitor strain on steel, or mounted on concrete surfaces using rock bolts installed through drilled holes to measure concrete strain. The built-in temperature sensor can simultaneously monitor ambient temperature.
BGK4000X is an integrated vibrating wire surface strain gauge, offering easy installation.
