A new compact, medium-resolution belt speed sensor from Siemens Energy & Automation is designed for any industrial application with belt-driven conveyor pulleys. The lightweight and durable Sitrans WS100 is suitable in applications from -40 to 230

Siemens Sitrans WS100 sensors
Siemens Sitrans WS100 sensors are available in standard and intrinsically safe versions and is NEMA 4/IP65 rated.

The sensor monitors the belt speed for input to an integrator, which calculates flow rate, total weight, belt load and speed of bulk materials. Typical applications for the Sitrans WS100 include the mineral processing industry, in particular quarries or cement plants, with belt speeds up to 392 ft/min (2 m/sec).
Magnetic mounting provides ease of installation, with no modifications needed. The magnetic holding force is up to 150 lb (68 kg). Constructed of polypropylene with type AISI 304 (1.4301) stainless steel sensor mount and cover, the unit includes corrosion resistant-components that are virtually maintenance-free. Additionally, the rotating targets are fully sealed ensuring safe operation.
The sensors can be combined with a Milltronics BW100 or BW500 integrator or Siwarex FTC PLC module, and a Milltronics belt scale for a complete weighing system.
