Senor Rollers

OWL-400 Cantilever Measuring Roller 

These measuring rollers are used for the measurement of web tension at machines with one-sided frame. The precise measurement of tensile force over the entire body width is ideal for narrow, sensitive material webs (e.g. in label printing machines). Different measuring ranges and mounting types cover virtually all areas of application. Precise web tension measurement of sensitive materials e.g. film, foil, non-woven fabric, paper, textiles, etc., ensure a high product quality and minimum downtimes.

OWL-500 Measuring Roller

Our OWL-500 series measuring rollers feature tried and tested measurement technology using double bending beams, combining high precision with robust design. The roller bodies are available in different materials. Roller surfaces can be provided with specific coatings on request (Teflon anti-stick coating, hard coating, chromium plating, rubber coating, ceramic, etc.). 
Dimensions and nominal forces can be adapted to suit the respective application. This allows clear indication of web tension variations and integration in the control process.
