Conveyor belt scale

Smart Belt Scale
Logo de la marque Hasler

Function :
The Smart Belt Scale is a conveyor belt scale specially designed for rugged outdoor environments such as quarries, gravel processing and mining. It is also well suited for any manufacturing process using conveyor belts, including: cement, fertilizer, chemical, tobacco, agro-food, etc… It is designed for easy installation which can be done by the customer’s own maintenance staff.

Technical sheet

Customer benefits

  • Accuracy : ± 0,2-0,5 %
  • Discharge totalization
  • No field calibration ever required (with digital load cells)
  • Easy installation thanks to the state-of-the-art mechanical design
  • High performances

Advantages

  • A single model adapts to all conveyor types and a wide range of widths.
  • Easy alignment of the weighbridge.
  • No special tooling required.
  • Totally prewired with cables and connectors supplied for error-free installation.
  • All operational parameters are pass word protected with 2 levels of security (hardware and software).

Entirely modular construction (height and width)

 

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 beltscale.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.

Controller

The Smart Belt Scale is connected to a BFC electronic controller - panel or wall version - having the following interfaces:

Standard

  • 3 Configurable isolated digital outputs with programable thresholds: totalizer, alarm, horn
  • 1 Configurable isolated 0/4-20 mA analog output for either: flowrate, current weight, speed, load per meter
  • 2 Configurable isolated digital inputs: out of range acknowledgement, totalizer reset.

Data Links

Isolated serial communication :

  • Modbus, Ethernet ModbusTCP, Profibus DP - for connection with a PLC or host computer.
