Abstract
A sensor device for detecting static modulus of elasticity in situ comprising: top and bottom frame end plates, the top and bottom frame end plates connected by frame side bars; a dry cavity connected to the top frame end plate and comprising a piston, precompression mechanism, and piston transfer plate; a displacement measurement gauge extending from the dry cavity along a longitudinal axis of the sensor device having a first end in contact with the piston transfer plate and a second end in contact with a bottom inner face of the bottom frame end plate; and a top inner face connected to the piston transfer plate wherein a portion of elastomeric material is positioned on the bottom and top inner faces, the elastomeric material positioned to prevent contact with either bottom or top inner faces except for a portion along the longitudinal axis of the displacement measurement gauge.
