  • FLM/WFLM series: Metal backing strain gauges

    The FLM/WFLM strain gauges are specifically designed to reliably measure strain on concrete surface. It features thin stainless-steel backings to prevent the penetration of moisture from the reverse sides. The WFLM series is integrated with moisture-proofing over-coating and integral leadwire to achieve reliable long-term measurement on underwater-curing concrete.
