1. A sensor device for measuring a linear elastic material deformation behavior comprising:
a top frame end plate and a bottom frame end plate, said top frame end plate and said bottom frame end plate connected by at least one frame side bar;
a dry cavity connected to said top frame end plate, said dry cavity comprising a piston and a piston transfer plate;
a displacement measurement gauge extending from said dry cavity along a longitudinal axis of said sensor device, said displacement measurement gauge having a first end in contact with said piston transfer plate and a second end in contact with a bottom inner face of said bottom frame end plate; and
a top inner face connected to said piston transfer plate wherein a portion of elastomeric material is positioned on said bottom inner face and said top inner face, said elastomeric material positioned to prevent contact with either the bottom inner face or the top inner face except for a portion along the longitudinal axis of the displacement measurement gauge.
