CONVEYOR BELT SCALE – LBS (LARGE BELT SCALE)BELT CONVEYORS FOR HIGH FLOW RATE AND SPEED
LBS Technical Sheet
Large Belt Scale:Depending on the application (high belt speed and / or flow rate), up to FOUR load cells can be sued as a multi-idlers belt scale. The load cells are connected to the same controller. Only one speed sensor is needed. HASLER can offer a solution also for changing belt directions.
Weighing,Flow rate calculation
TotalizationAll materials conveyed on a belt conveyor
Accuracy: from ±0,5%Discharge totalizationNo field calibration ever required due to 100 % digital load cells Easy installation thanks to the state-of-art mechanical designA quality product of HASLER
Function: The Large Belt Scale is a conveyor belt scale specially built for outdoor environment in surface mines on belt equipment and mine equipment. It is possible to install the LBS in all known conveyor types (also garlands stations). Please demand our reference list.

Speed sensor :
The HASLER speed sensor is supplied in an extremely rugged execution. The arm is made of stainless steel. The wheel is out of aluminium with profiled thread. The wheel is pressed under the upper run about a tensioning element. By this the unit is protected against dirtying, humidity and ice on the lower run.
Flexible and multi-variant construction
Easy maintenance and commissioning
Suitable for highest speeds up to 7,0 m/s
Flow rates up to 20.000 t/h and counting
Low maintenance
Suitable for all conveyor types
Controller: The Large Belt Scale is connected to a BFC electronic controller - panel or wall version - having the following interfaces:
Standard3 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 meter2 Configurable isolated digital inputs:
out of range acknowledgement, totalizer reset.
In optionIsolated serial communication:• Modbus, Ethernet ModbusTCP, Profibus DP - for connection with a PLC or host computer.

The “Large Belt Scale” is offered in four versions. Depending on the application and the belt plant HASLER could submit you a perfect solution. All types have a safety gear execution for the emergency.
Typ 1 (Standard):IPE girder with suspension for load cells and tacho suitable for all standard conveyor belts.
Typ 2:Installation kit with fix idler stations and threaded rod for height ajustment.
Options:Additional module for varying conveying directions.
Typ 3:Installation kit with height alignment by means of joint plates
Typ 4:Installation kit for direct weighing of garland idlers.
Here is a separate material weighing absolutely necessary due to technical reasons.
Specification: Accuracy: 0,5 – 2,5 % (if installed in an approved conveyor in accordance with the manufacturer’s specification)Temperature range: -25 °C to +60 °C (-13 °F bis +140 °F)Protection class: IP65Belt speed: 0,05 bis 7,0 m/s in case of one weighing stationFlow rate: 20.000 t/h and countingSlope oft he belt: ≤ 20°, material should not tumble backwardsMax. trough angle: ≤ 45°Load cell: 100 % digital SFT (Smart Force Transducer)Standard Colour: RAL 5000 (blue)
