Patent ID: 6931915

Claim:
An improvement in a rheometer in which strain is effected in a test specimen while temperature is measured in the test specimen, the improvement comprising: a test specimen temperature information sensor for juxtaposition in close proximity with the test specimen to provide information pertaining to the temperature of the test specimen; a test specimen temperature information transmitter circuit for receiving test specimen temperature information from the test specimen temperature information sensor; the test specimen temperature information sensor and the test specimen temperature information transmitter circuit being movable through movements corresponding to the strain effected in the test specimen; a test specimen temperature information receptor circuit juxtaposed with the test specimen temperature information transmitter circuit and being placed at a stationary location relative to the test specimen temperature information transmitter circuit; an isolator arrangement isolating the stationary test specimen temperature information receptor circuit mechanically and electrically from the movable test specimen temperature information transmitter circuit; and a temperature information transfer system for passing test specimen temperature information from the movable test specimen temperature information transmitter circuit across the isolator arrangement to the stationary test specimen temperature information receptor circuit without a direct mechanical or electrical connection between the movable test specimen temperature information transmitter circuit and the stationary test specimen temperature information receptor circuit.
