OnTop Online Measurement
Measuring surface topography in real-time.
The online or inline version of OnTop is meant to be installed directly against a moving but stabilized surface web, for instance against a reel, extracting real-time surface information from the surface web. The device has been installed successfully in paperboard manufacturing machines.
The online/inline device gives roughness average (Ra) values and spatial wavelength spectra in real-time. The online device installed against a paperboard reel.
