CR – Compact force sensor with flexible installation options for pulleys in static applications

  • 3 sizes with shaft journal diameters of 8, 10 and 12 mm
  • Nominal force ratings from 50 N (11lbf) to 1500 N (330 lbf)
  • Measuring range 20:1, accuracy class ±0.5%
  • Options include high temperature and vacuum chamber (to 10-7 hPa) construction
  • Overload protection rating of 10-times nominal force, stainless steel sensor body

The CR-Series force sensor offers compact dimensions and flexible installation options, and are designed for the measurement of tension on continuous material processing lines for filament materials. This product will accept a huge variety of different standard pulleys and therefore be applied versatilely. The product can be supplied with a Pilot or without a Pilot at the back the unit. In addition, flexible mounting options include the ability to install the unit utilizing either four fasteners from the front or a single fastener from the rear. The included dowel pin can also be incorporated between force measuring bearing and the machine frame to ensure proper unit orientation. For installations where a Pillow Block mount is required the optional bracket can be utilized. Shaft journal diameters of 8, 10 and 12 mm allow easy installation of standard pulleys. Standard pulleys are not supplied by FMS.
