FIELD: textile industry.
SUBSTANCE: device for monitoring of fabric feed availability at textile machine inlet comprises capacitance sensors, self-contained generators, mixer, narrowband resonant amplifier, detector, low-pass filter, DC amplifier, count trigger, high-frequency amplifier, frequency detector, comparator, amplifier of control signals, high-frequency amplifier, frequency detector, comparator and control signal amplifier. Inlet of high-frequency amplifier is connected to outlet of one of self-contained generators, and outlet of high-frequency amplifier is connected to inlet of frequency detector, outlet of which is connected to inlet of comparator, which is connected to inlet of control signal amplifier.
EFFECT: device provides for control of fabric feed continuity at machine inlet, automatic shutdown of machine in case fabric feed is interrupted and actuation of control alarm.
