CONVEYOR BELT SCALE
Function :
An electro-mechanical weighbridge with two digital SFT (Smart Force Transducer) load cells is inserted into the apron conveyor for the accurate flowrate measurement.
No weighbridge misalignment error thanks to virtually deflection free measurement by the SFT
Smooth, vibration free weight acquisition thanks to uncut rails in the weighing area. This eliminates the weighing errors with traditional scales caused by the rollers passage over the rail cut.
The conveyor speed is measured by an incremental encoder mounted on the drive shaft.
Functions
- Weighing
- Flow rate calculation
- Totalization
- Dosing of materials conveyed on an apron conveyor
Customer benefits
Advantages
- Design is individually adapted for the existing apron conveyor
- For steel plate or deep drawn bucket conveyors
- Installation in horizontal (preferred) or inclined part
- Optional hot temperature design for up to 150°C
Applications
The Smart Apron Scale (SAS) is an apron conveyor belt scale. It allows to check the real production of the kiln and to determinite the ratio between rawmeal, clinker and combustibles.
Rails
- Standard rail size S20 compatible S18
- Special rail size on request
Controller
The Smart Apron Scale is connected to a BFC electronic controller – panel or wall version.
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.
In option
Isolated serial communication :
- Modbus, Ethernet ModbusTCP, Profibus DP - for connection with a PLC or host computer.
