  • Peripheral gauge
    Patent number: 5767413
    Abstract: A gauge for measuring a dimensional change, such as a change in the periphery of a test object, is an elastomeric tube filled with an electrically conductive fluid such as mercury. The gauge can be formed into a loop around the test object. Thereafter, any change in, e.g. the circumference of the test object is monitored by measuring the change in resistance (or voltage) between the ends of the tube.
