For monitoring strand tendons is a spiral strain gauge comprising a Teflon® coated resistance wire extending between two hard rubber end anchors.
It is a highly effective, simple to use means to examine load and strain in rock and soil anchors and also in cable bolts used for rock support.
Used to measure load and strain in rock and solid anchors in the bond or stressing zone and in pre-stressed and post-tensioned concrete.
- Exceptional linear response and accuracy in a low-cost system
- Simple to use and implement on site
- Sturdy design provides ultimate reliability and durability
- Performance not compromised when embedded in concrete or surrounded by grout
- Water resistant
