LS31HT & TS81HT: Weldable Strain Gauges for Rough Environments and High Temperatures

The LS31HT and TS81HT weldable strain gages are suitable for spot welding to steel structures and materials. They are ideal for use in the field where the cleanliness required for gluing cannot be guaranteed, for example on construction sites or in manufacturing plants, and can withstand adverse conditions. Such conditions would likely damage the adhesive bond of conventional strain gauges. The weldable strain gauges are mounted by a simple spot welding process that requires little practice*. They are fitted with 0.5m stranded connection wires. 

Typical applications for LS31HT and TS81HT include the mechanical load analysis on bridges, piles, tunnels, buildings, pipelines, wind power plants, and tanks. 

 

*HBK recommends the C33 spot welding machine from VBS-Fügetechnik AG.

Robust

  • Comes on a carrier plate covered with silicone rubber to be spot welded

Withstands harsher operating conditions

Simple to install

  • Easily mounted by simple spot welding method that requires hardly any preparation

Long service life with a permanent attachment to the structure

Reliable

  • Withstands elevated temperatures from -50°C up to +250°C (short time 300°C). 
  • 4-wire configuration

Accurate results under harsh conditions or environments
