About FLM/WFLM Series Metal Backing Straingauges for Concrete Material

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.

Temperature compensation materials

  • 11: Mild steel

Used leadwire: 0.09mm2 3-wire crosslinked polyethylene sheath leadwire (2m standard) with a total resistance of leadwire per meter: 0.4Ω
