| To increase the productivity, ever higher speeds are required during wire processing. Dancing roller controls can hardly keep up with the fast changing tensile forces incidental high-speeds, but tensile forces that are too high can strain the wire and thereby affect the strength and the diameter of the wire. Unfortunately, these forces can be quickly reached, in particular when manufacturing fine wires.
The reliable radial force sensors, which are used for tensile force measurement on wires, cables, fibre optics, take-ups, pay-offs and winding systems, are optimal to serve that purpose, because of their reaction speed. For tensile force measurement on very fine wire and very small tension, the German company Tensometric has recently developed a radial force sensor, model M 390 - FD. Tensile forces < 1cN can be reached, indicated and controlled. For this range, 3-roller systems are also available. Because of their built in amplifier, it is easy to integrate this sensor in existing machine control panels.
