Withstands harsher operating conditions
LS31HT: Weldable Strain Gauge for Rough Environments and High Temperatures
The LS31HT is a weldable strain gauge to be spot welded to steel structures and materials. It is ideal to be used "on site", when the cleanliness required for gluing cannot be guaranteed, for example on construction sites or in production plants, withstanding hazardous conditions. Such conditions would likely damage the adhesive bond of conventional strain gauges. The LS31 strain gauge is mounted by a simple spot welding process that requires little practice. It is fitted with 0.5-m stranded connection wires.
Typical applications for LS31HT include the mechanical load analysis on bridges, piles, tunnels, buildings, pipelines, wind power plants, and tanks.
We recommend using the VBS Fügetechnik c33 spot welder to install weldable strain gauges.
