Milltronics RBSS monitors conveyor belt speed, with the output
signal transmitted by cable connection to the integrator
(Milltronics BW500, or SIWAREX FTC).
Easily installed close to the belt scale assembly, the RBSS provides a signal generated as the wheel on the sensor rotates on
the return belt. To secure this cost-effective unit in place, position
a cross bar between stringers - either just before or after a return
belt idler, or use the optional mounting bracket. The weight of the
RBSS ensures positive rotation of the wheel in the middle of the
return belt, and pulses from the magnetic sensor are generated
by the rotation of the 60 toothed speed sprocket driven by the
wheel.
The RBSS output can be applied to any Milltronics belt scale integrator.

Approvals for RBSS IS are based on internally mounted NAMUR
slotted proximity switch (Pepperl+Fuchs #NJ0.8-5GM-N) and use of
suitable IS switch isolator (amplifier). Please see RBSS operating
instructions for more information.
Approval ratings for the proximity switch and IS switch isolator are the
property of Pepperl+Fuchs. Copies of these Approval Certificates
may be obtained at http://www.siemens.com/processautomation.
