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.

Applications:

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.

Features:

• 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
