Peremes feszítés mérőcellás rendszerek

A peremes feszítés mérő cellák felhasználhatók a szalag feszességének szabályozására gyakorlatilag minden olyan feldolgozóüzemben, ahol tekercs típusú anyagokat dolgoznak fel, vagy készítenek. Különösen a feldolgozó állomások előtt alapvető fontosságú, hogy az anyag folyamatos feszítéssel kerüljön továbbításra.

FUNCTION

The load cell used for web tension control comprises a stable outer ring with flange cover and centering collar for precision assembly. The inner ring in the form of a bi-directional strip ensures centered mounting of the ball bearing. The radial forces created by the web unbalance the strain gauges linked together to form a measuring bridge on the inner ring. This leads to an analog output signal proportional to the web tension.

AREA OF USE

Flange load cells can be used for web tension control in practically all processing plants where web-type materials are processed or finished. In front of processing stations, in particular, it is of fundamental importance that the web is transported with a continuous web tension.

APPLICATION

With a 90° horizontal-vertical wrapping angle on the measuring roller and a horizontal measuring direction, optimum web tension measurement is assured. Only detection of the bearing forces on both sides by the tension sensor can prevent incorrect measurements caused by the web moving sideways and asymmetrical web tension distribution. Load cells incorporated in a closed loop should be mounted as near to the actuator as possible.

  • Reliable web tension monitoring helps avoid web tears and thus reduce producion costs.
  • E+L load cells continuously record the tension in the moving web and supply this value as an analog signal. As such, they provide the prerequisite for reliable web tension measuring and control.
