ZMGZ – Force sensor rolls without shaft

  • Nominal force ratings from 50 N (11lbf) to 1500 N (330 lbf.)
  • 25 or 35 mm shaft journal for standard bearings
  • Options include high temperature and vacuum chamber (to 1E-7 hPa) construction
  • Measuring range 30:1, accuracy class ±0.5%

The ZMGZ-Series force sensor offers flexible installation options, and are designed for the measurement of tension on continuous material processing lines where idler rolls with integrated bearings without shaft are utilized. The product is available in two sizes. The shaft journals of 25 or 35 mm diameter accept standard bearings.
