About the WFLM 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.
0.09mm2 integral crosslinked polyethylene sheath leadwire of 2m standard included.
Integral leadwire length longer than 2m is available.
Total leadwire resistance per meter : 0.4Ω
