About the WFRA Series Waterproof Straingauges
Our WF-series water proof type strain gauges eliminate the need for moisture-proofing coating, which is sometimes troublesome in a field test. They have a pre-attached vinyl leadwire and an entire coating with epoxy resin. The coating is transparent and flexible, which ensures easy installation of the gauge. By merely bonding the gauges with CN or P-2 adhesive, outdoor or underwater measurement for a short-term becomes possible. These gauges are also effective in omitting primary coating in case of applying a multilayer coating.
