| Description: | Special Report Abstract: Due to recent problems experienced with strain-gage based transducers immersed in water at below-freezing ambient temperatures, a test program was conducted to determine if commercially available strain-gage waterproofing systems could withstand these conditions. A total of 96 combinations of eight waterproofing systems, three beam materials, and four strain gage adhesives were evaluated. Test environments included strain cycling at temperatures from +32°F to +75 °F and freeze-thaw cycling from -35°F to +90°F . Only one waterproofing system withstood all tests with no failures. Other results ranged from one installation failure on three systems to the failure of all 12 installations of one system |
