Abstract
The invention relates to a miniature yarn tension measuring sensor. The miniature yarn tension measuring sensor comprises a shell, a support base, a porcelain tube, an elastic element, insulating damping adhesive, sealing tape, screws, a gasket, nuts and a transmitter circuit board. In the conveying process, yarn passes through the porcelain tube of the miniature yarn tension measuring sensor in a pressing mode at a certain angle, under the action of yarn tension, the porcelain tube is pressed downwards to cause deformation of the elastic element, a strain bridge converts induced deformation into electric signals in proportion and transmits the electric signals to the transmitter circuit board, and the transmitter circuit board amplifies and outputs the electric signals to a yarn conveyor control module.
