The Eltex Tension Monitor (ETM) is an on-line device for sewing machines
and similar applications. The device monitors the thread tension and also acts as a
thread break detector. It enables the operator to keep the thread tension within the
desired tension range for best operation and quality of the seam.
The ETM indicates, with LED’s, if the thread tension is outside the selected Indication
Limits. If the thread tension goes outside the selected Stop Limits, the ETM will
generate a stop signal to the machine.
