By using Eltex Tension Monitor ETM RS422 the seaming quality will be improved. This tension sensor will not only monitor the thread tension, but also acts as a thread break detector.
The ETM RS422 sensor has an interface designed to communicate with the sewing machine’s control computer. The thread tension varies during the stitch, and it peaks when the tensioner tightens the stitch. The Eltex sensor detects this peak tension and consistently transmits the values to the control computer.

The sensor ETM RS422 can be used everywhere when there is a demand for high-quality sewing. For manufacturers of car seats when airbags are in the car’s seat, it is crucial to have control of all parameters. Thread tension is one of these parameters.

Over time it is necessary to calibrate the tension monitors and the International Automotive Task Force (IATF) requires that all laboratories that carry out calibration are accredited.
