Érzékelő henger rendszerek

A szalag feszítés szabályozásához használt érzékelő hengereken két tehermérő elem van beépítve a görgő testébe. A mérési erőt egy kétirányú szalagon keresztül észleljük, amelyre a feszültségmérőket alkalmazzuk. Ennek eredményeként a szalag feszítéssel arányos analóg mért jel kerül kiadásra.

FUNCTION

On the sensor rollers used for web tension control, two load cells are already integrated in the roller body. The measuring force is detected via a bi-directional strip to which the strain gauges are applied, as a result of which an analogue measured signal proportional to the web tension is output.

AREA OF USE

Sensor rollers can be used for web tension control in practically all processing plants where web-type materials are processed or finished. The compact sensor rollers are the preferred solution particularly in situations where space is very restricted or on single-column machines.

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.
