Strain gauges
SVWG Vibrating-wire strain gauge
Vibrating-wire sensor for structural strain monitoring. Analog and digital versions include temperature measurement.
Application
Application and connection
The digital output supports measurement chains with several dozen vibrating-wire gauges and line lengths up to 800 m, avoiding separate vibrating-wire data loggers for those sensors.
Surface-mounted by minimally invasive spot welding on metal or by anchor bolts on concrete.
