VW Arc-Weldable Strain Gauge
VW Arc-Weldable Strain Gauge has a steel cord with two ends fixed on a metal rod. When the metal rod sustains a micro deformation caused by an external force, the vibration frequency of the steel cord varies according to the deformation. Such gauges can be installed on rod elements of steel structures to monitor stress distribution.

Introduction
VW Arc-Weldable Strain Gauge has a steel cord with two ends fixed on a metal rod. When the metal rod sustains a micro deformation caused by an external force, the vibration frequency of the steel cord varies according to the deformation. Such gauges can be installed on rod elements of steel structures to monitor stress distribution.
Applications
Monitoring distribution of load in pile tests
Monitoring areas of concentrated stress in pipes
Measuring strain in tunnel linings and supports
Monitoring load in struts used to brace deep excavations
Monitoring structural members of buildings and bridges during and after construction
