Optimized measurement, Proven safety

Micro strains ( ) are collected by the vibrating wire strain gauge which is tensioned steel wire in stainless steel tube works correlative deformation of steel and concrete structure.

The tension in the wire is plucked by an electromagnetic coil and measured resonant frequency.
