Designed to be embedded in concrete

A fibre optic strain sensor designed to be embedded in concrete. It may be cast directly into a wet mixture or encapsulated into a concrete briquette to be cast into a wet mixture. Intrinsically safe, it is immune to EMI, RFI, and lightning. It allows static/dynamic measurement and can deliver signal transmitted over long distances with no interference due to fiber bending.
