Smart Belt Scale, Single, Twin and Double (Multi-Station)

Depending on the application (high belt speed and / or flow rate), up to four single idler SBS can be combined to be used as a multi idlers belt scale. The SBS are connected to the same controller. Only one speed sensor is required, either a friction wheel speed pick-up or an incremental encoder mounted on the return drum
