ABSTRACT:
According to the present invention, the respective fluid pressures at the output sides of the plural jet fluid valve units in a fluid jet loom are converted into electrical signals by respective pressure detection elements such as piezo-electric elements. An alarm lamp or buzzer is activated or the loom operation stopped unless all of the electrical signals supplied from the pressure detection elements associated with the valve units reach preset values.
