Self balancing measuring probe enclosure and method for waterproofing same
Gábor Fodor, Rune Nilsen · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 1991
Waterproofing standard linear position measuring transducers often requires a sacrifice in measuring accuracy when the transducer must be used at varying water depths. To obviate this disadvantage, the disclosed waterproofing structure is constructed such that increasing or decreasing forces applied to the transducer as its depth in the water changes will not apply unbalanced forces to the transducer thereby causing false readings. Similarly, the nominal gauging force developed by the instrument is unaffected by varying water depths.
