CA – Compact force sensors with flexible installation options for use with dead shaft rolls

  • Compact dimensions and various installation options
  • Nominal force ratings from 50 to 1500 N (110 to 330 lbf.)
  • Options include high temperature and vacuum chamber (to 10-7 hPa) construction
  • Measuring range 30:1, accuracy class ±0.5%
  • Overload protection rating of 10-times nominal force, stainless steel sensor body

The CA-Series force measuring sensor offers compact dimensions and flexible installation options, and is designed for the measurement of tension on continuous material processing lines where dead shaft idler rolls are utilized. 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. Adapter diameters are available in various dimension, in metric as well as in imperial sizes.
