1. A system for monitoring tension and breakage of yarn in a textile machine having:
a sensor bar containing multiple eyelets to receive the yarn, each of the multiple eyelets containing at least one sensor to generate new signals as the yarn passes through each of the multiple eyelets; and
a microprocessor containing software, the microprocessor when running the software being in communication with each of the at least one sensor to receive and analyze the new signals created by yarn motion, and in two-way communication with the textile machine, and configured to perform operations comprising:
a. entering user defined broken yarn set point;
b. entering user defined tight end set point;
c. starting the machine;
d. initiating by the software a predefined empirical broken yarn control limit inherent within the software;
e. initiating by the software a predefined empirical tight end control limit inherent within the software;
f. constantly scanning each of the at least one sensor;
g. transmitting the new signals from each of the at least one sensor to the software run by the microprocessor; and
h. continually analyzing the new signals from each of the at least one sensor to generate new signal data.
