ABSTRACT:
A strain gauge sensor for measuring the unit weight of a moving sliver in a textile machine, comprising a support rigidly mounted on a sliver output end of the textile machine and a trumpet carried by the support for outputting a condensed sliver. At least one strain gauge is carried by the support and responsive to strain imposed on the support by movement of sliver through the trumpet. Electrical circuit is means carried by the support in electrically communicating relation to the strain gauge, and includes a power supply and amplifier carried by the electrical circuit on the support for outputting an excitation voltage and a Wheatstone bridge for receiving the excitation voltage from tile power supply and applying the excitation voltage to the at least one strain gauge, receiving a feedback signal from the strain gauge and outputting a control signal corresponding to the weight of the sliver passing through the trumpet.
