Abstract
The admission of pressurized fluid into the weft insertion nozzle of a loom is detected by an electrical signal generating means arranged in the nozzle in communication with the fluid delivery passage through the nozzle, the generating means generating a signal indicative of such fluid admission and applying the same to a conductor extending to an exterior point for use in monitoring the proper operation of the loom. Preferably, the signal generating means is fluid pressure responsive, such as a piezoelectric crystal exposed to the fluid pressure in the nozzle passage.
