Abstract
A temperature compensating strain gage for measuring elongation of parent elastomeric material. The strain gage comprises an elongated elastomeric strap having the same or similar temperature characteristics as the parent elastomeric material, a clamp secured to the parent material for securing one end of the strap, a transducer, a pair of side by side spaced apart transducer mounts, one of the mounts is attached to the free end of the strap and the other is attached to the parent material, a heat transferring medium is positioned between the parent material and the strap intermediate the ends and a strain gage element is mounted on the transducer.
