Eltex thread break sensors are essential for preserving quality seams on all types of sewing machines. Eltex sensors detect the movement of the sewing thread and immediately stop the machine when a thread break occurs. The sensors are insensitive to dust and dirt and can be used with all thread counts and thread types.

All Eltex tension monitors are tested before delivery. At the test we check that the new unit fulfills the specifications mentioned in the documentation of the ETM unit.
When we calibrate we check that the units fullfills the same specification as when it was produced. The calibration method we use for the ETM RS422 units is accredited according to the Standard ISO/IEC 17025.

ETM units that are sent for calibration / repair are calibrated at our headquarter in Osby, Sweden. Please send units that need calibration to our address and give us a notice in advance to check for availability. During normal circumstances the handling time will be one working week from arrival to Eltex.
