Abstract
The present invention relates to equipment for monitoring the yarn travel on a textile machine, particularly in the shuttle of a weaving loom, comprising a piezoelectrical yarn sensing unit mounted in the shuttle and an electronic receiving circuitry outside the shuttle. The sensing unit transmits yarn travel signals of a frequency which is determined by one of the natural frequencies of the sensing unit, and the electronic receiving circuitry comprises at least one resonant circuit tuned to that natural frequency.
