ACE - Model 1210 VW - Spot Weldable Strain Gages - Datasheet

The model 1210 VW spot weldable strain gage consists of a gage that is composed of two end flanges joined by a tube, and a coil housing that two small plucking coils are fixed. The vibrating wire of VW spot weldable strain gage is tensioned between two end blocks which are spot welded to the surface of the steel member. The wire is plucked so that it vibrates at its resonant frequency. This frequency depends on the wire tension, which will vary as the strain of steel member. The change in frequency is calculated the strain or stress directly by the VW readout unit.
