The RMGZ series force measuring roller is usedto measure the tension in wire, cable and similarmaterials. An application specific sheave or pulley ismounted to the two lifetime lubricated ball bearings. The force measuring rollers applythe force to the measuring web ina parallel plane as opposed to atypical bending beam. This ensuresmaximum accuracy and measuring sensitivity. Four foil-type strain gauges configured in a full Wheatstone Bridge are utilized to measure the materialtension. A mechanical hard stopensures the highest overload protection and makes the sensor virtually indestructible. This combination guarantees thehighest accuracy and reliabilitywithout the need for recalibration. - Nominal forces from 6 8000 N- Sizes available for every application- 10 times overload protection: No recalibration required- 20 : 1 force measuring range:Wide measuring capability- Lifetime lubricated ball bearings:No maintenance necessary
