VW Strain Gages

Vibrating Wire (VW) strain gages are used for tracking long-term strains due to relatively slow structural movements. They can survive in very harsh environments for years. Both surface-mount and embedded models are available. Not suitable for dynamic or live-load strains.

• Bending moment strains in bridge piers due to scour
• Retaining wall bending stresses during construction
• Building wall movement due to seasonal weather changes
