Web Tension With Measuring Rollers
Measuring rollers provide complete mechanical systems for web tension measurement. The customer receives either all components he needs to install a measuring roller from a single source or he receives a completely assembled measuring roll with internal force sensors and optional with integrated electronics as one part. Depending on the application and load range different types are used.
For individual questions, we will help you

For example:
Sensors for built-in roll mounting, also for flatness measurement rolls
For special requirements, especially for large roll diameters, HAEHNE can supply sensors for mounting into the roll shell. This makes it possible to build segmented rolls, e.g. for flatness measurement and also for nip force measurement in winders.
