Abstract
A thermomechanical analysis apparatus includes a probe assembly supported in substantially weightless contact with a sample material over a range of displacement of the probe by means of a linear motor controlled from a constant current source. The probe assembly is automatically weighed by measuring and storing the value of the current needed to raise the probe, that value is thereafter employed during the analysis mode to maintain the probe assembly in a substantially weightless condition.
