RMA-CSW Cantilever measuring rolls are used for direct tension measurement in narrow webs of films, foils, tapes, textiles or metals. Defined and setpoint-controlled web tension ensures high product quality and is the basis for a minimum of machine downtimes.
The compact RMA-CSW measuring rolls fulfill 2 functions at once:
- measurement of tension in the web
- guiding and deflecting the product web
- 2 construction sizes, available in 10 rated load ranges:
- 0 to 100 N ... 0 to 400 N, SR - Standard Range
- 0 to 500 N ... 0 to 1500 N, HR - High Range
- 0 to 3000 N, XR - eXtended Range
- Direct, radial force transfer
- Lever arm independent
- Easy installation thanks to flange mounting
- High precision and excellent long-term stability
- High spring constants for the sensor permit high rotation speed ratings for the deflector roll
- Compact design
