FLM Series Metal Backing Straingauges for Concrete Material

Single element straingauge which prevents the penetration of moisture

About the FLM Series Metal Backing Straingauges for Concrete Material

FLM/WFLM series metal backing strain gauge
These strain gauges have thin stainless steel backings which prevent the penetration of moisture from the reverse sides. This construction is aimed for successful strain measurement on concrete surface. The WFLM gauges have moisture proofing over-coating and integral leadwire in addition to the stainless steel backing. It is intended for long term measurement or measurement on underwater-curing conctrete.
