RMA-DS Radial Force Measuring Axle

RMA-DS Radial Force Measuring Axle
Click images to enlarge.
RMA-DS sensors are used for direct tension measurement in moving webs of paper, films, foils, textiles or metals.The dead shaft of a web guiding roll is supported in the clamping adaptors of two RMA-DS sensors. Measurement of the web tension is effected by registering at both sides the radial bearing forces on a web guiding roll.

Defined and setpoint controlled web tension ensures high product quality and is the basis for a minimum of machine down-times.

The compact RMA-DS sensors in connection with a web guiding roll fulfill 3 functions at once:

  • measurement of tension in the web
  • bearing of the shafts and rolls
  • guiding and deflecting the product web

Features

  • Direct, radial force transfer
  • High spring constants for the sensor permit high rotation speed ratings for the deflector roll
  • Nominal forces differing from standard
  • Advanced temperature range
  • Easy installation thanks to flange mounting
  • High precision and excellent long-term stability
  • Sensor housing and measuring cell made out of stainless steel, for use in humid environment
