Applying resonance muffler of electron radiation technology to wire and cable material can change its physical structure through electron accelerator radiation, improve the tensile and combustion resistance of wire and cable, prolong its service life, improve product performance and quality, and enhance market competitiveness. According to the change of dry cotton thickness, the output changes from - 5V to + 5V. 0V is the basic center and 0V is the appropriate dry output. When there is no dry cotton thickness, the sensor requires shielding the output signal. This kind of sensor needs to adapt to the environment where the temperature and humidity change greatly in cotton spinning workshop, and the ZP muffler can work normally after human contact with more dust. Required output voltage change: 4-6g cotton sliver per meter, there is 1-2v voltage change, this voltage needs to be adjusted, the standard weight adjustment range of cotton sliver is 12-15v, the adjustment range is about 5-6G per meter plus or minus 5%. The outgoing line requirements are two lines of working voltage and two lines of output voltage (i.e. signal voltage), i.e. the voltage change required when the importance of cotton thread changes.
