Abstract
A fluid jet loom includes a source of pressurized fluid, a magnetic valve, and at least one nozzle, such as a weft insertion air jet nozzle, as well as at least one flexible pressure hose connecting and providing pressurized fluid from the magnetic valve to the nozzle. In order to detect any hole, rupture or separation of the pressure hose, the hose includes at least one electrical conductor embedded in or arranged on the hose wall. An electrical current flows through the electrical conductor, which preferably forms a conductor loop and especially a resonant circuit loop. By monitoring an electrical characteristic, such as the resonant frequency, of the electrical signal received from the conductor loop, any disruption in the pressure hose can be immediately detected as a change in the monitored electrical characteristic, which in turn causes a loom stop signal to be generated.
