VWS-5/10F Smart Vibrating Wire Surface Strain Gauge for Steel Plate and Structure Monitoring
VWS-5/10F Smart Vibrating Wire Surface Strain Gauge is designed for long-term installation on the surface of hydraulic structures or other structures. It measures surface strain variation of the structure and synchronously measures the temperature at the installation point. The surface strain gauge adopts a full stainless steel integrated structure with anti-rotation, anti-bending, impact-resistant and drop-resistant design. It provides grounding lightning protection and can work underwater for long periods. Its low elastic modulus gives good follow-up performance with the measured structure and helps avoid disturbance to the original stress field.
