Measuring roll MUW-1

Scope of Supply Measuring roll with two force sensors , each with 5 m cable (PVC). Cable connection variant depending on the sensor Additional Option F: For use in explosive areas, incl. J-Box Additional Accessories Bearing support blocks Available models of the measuring roll Ordering Example MUW120-650-910-F Type Roll diameter Roll length (BL) Overall length (GL) Variants / Options Special Features • Measuring roll with mounted web tension sensors • Measuring range from 200 up to 30 000 N • Separate or joint measurement of bearing forces • Cost effective compact design, simple installation • Roll diameter and surface treatment according to customer specification The measuring roll MUW is used to measure web tension forces, e.g. in moving webs of paper, textile, plastics, metal. The compact design enables quick and cost effective integration into OEM machines or retrofitting into existing machines. The MUW consists of the roll with shafts and the radial force sensors BZA or BZN. Bearing support blocks LBZR are supplied on request. The roll can be delivered according to customer requirements with regard to dimensions, type of material and surface treatment. Rolls can be ordered in steel, stainless steel or aluminium, also with coating. The measuring sensors can be mounted directly onto the machine frame or with mounting brackets.
