Method and apparatus for determining a temperature of an inductively heated godet by measuring current through and voltage across a primary winding

摘要

The temperature of a galette or godet is determined for the godets of a spinning machine for synthetic yarn, by evaluating the calibration curve for temperature as a function of voltage and current of the primary windings of the godets and a correction factor is established for temperature as a function of voltage. The automatic control is provided to effect that evaluation.
