Dilatometer
Abstract
A dilatometer mountable to the exterior surface of pressurized pipe to measure small pressure variations within the pipe. The dilatometer includes two rigid beams tied together by nonextensible tensile members on opposite sides of the pipe. One member includes a strain gauge mounted to a strain gauge plate. Dilation of the pipe distends the beams, stressing the gauge plate. The strain is physically magnified on the gauge plate due to its position at the end of the beams and in direct proportion to overall diametral variation of the pipe due to pressure fluctuations.
