Objective of yarn clearing -     Objective of yarn clearing is to remove objectionable faults from the yarn / supply package Principles of measurement of yarn faults/Yarn diameter    Two principles are used in morden winders for identification of yarn faults   1. Capacitance principle    2.Optical principle  1.Capacitance principle - Working Principle- :    When yarn pass through two capacitor parallel plate the electrical signal changes / produce which is proportional to change in mass per unit length.  Capacitance (C) = εA /d                                 C= charge/Voltage Working -:       In the capacitor electronic yarn clear device is measurement of yarn mass per given test length        Any change in mass of yarn then the set value to makes corresponding change in a capacitance. The signal is send to the amplifier.  The amplifier amplifies the signal and compared with previously set value in the discriminator . If the limit is goes above the set v
