FIELD: textile, paper.
SUBSTANCE: device for detection of fabric seam and monitoring of warp value comprises capacitance sensors, self-contained generators, mixer, resonant controlled narrowband amplifier, amplitude detector, low pass filter, DC amplifier, count trigger, frequency detector, amplifier of frequency detector signal, filter of frequency detector signal, control element. Mixer outlet is connected to signal inlet of resonant controlled narrowband amplifier connected to frequency detector connected via amplifier of frequency detector signal with inlet of frequency detector signal filter connected to control element joined with its outlet to control inlet of resonant controlled narrowband amplifier.
EFFECT: application of this device makes it possible to expand functionality and to increase efficiency of device operation due to option of self-tuning in case of fabric cod change and ambient parametres variation.
