The VWS-2100 series vibrating wire embedment strain gauges are designed for direct embedment in concrete.
The VWS-2000 series vibrating wire surface mount strain gauges are designed for the long term monitoring of steel or concrete structures. Gauges may be attached to steel structures by arc welding or, using alternative end blocks, bonded or grouted into concrete.
The Strain Gauge, sometimes known as a Demec Gauge shown here consists of a digital dial gauge attached to a bar. A fixed conical point is mounted at one end of the bar, and a moving conical point is mounted on a knife edge pivot at the opposite end. A setting out bar is used to position pre-drilled discs which are attached to the structure using a suitable adhesive.
The VWS-4000 series vibrating wire Sister Bars and Rebar Strain Meters are designed to be embedded in concrete to measure strains due to imposed loads.
