ABSTRACT:
An improved measuring device for measuring the unit weight of sliver as it passes through a trumpet includes a trumpet gauge plate for supporting the trumpet and a pair of weighted elements mounted on each side of the plate. The plate includes upper, lower and central portions wherein the lower portion includes an opening for supporting the trumpet and the central portion has a reduced cross section. A plurality of strain gauges for detecting deflections is mounted on front and rear surfaces of the central portions adjacent the lower portion and the weighted elements. The strain gauges are electrically connected in a modified Wheatstone Bridge configuration. Deflection sensings in strain gauges adjacent the weighted elements cancel out deflection sensings produced by external vibrations to produce an accurate measurement of the sliver weight.
