Belt Scales

Belt Scales

John White & Son Weighing Solutions offer a broad range of Conveyor Belt Scales.

Each model guarantees the possibility of one or more alternatives for every application. Within different markets, there are many ways to use a belt scale to measure the actual flow on a conveyer belt which can also be used for dosing your product.

Examples of markets in which belt scales are frequently used:


Operation of Belt Scales

A belt scale consists of a weigh frame with one or more load cells, speed pick up and a weigh processor, which integrates the two signals (kg/m and m/s) into a value of kg or tons per hour.

The selection of the weigh frame and speed pick up is determined by the requested accuracy, variables like belt speed and inclination of the belt, the structure of the transport belt, and external circumstances like moisture and aggressive environment.

Belt Scales Indicator

The model WE503 is an approved weigh processor, which can be used
in most applications for dynamic weighers, like Belt scales, Screw
weighers, Bulkslide Flowmeters and Impact Flowmeters.
It provides a readout of the actual flow in kg per hour (or ton/hour)
or the total in kg (or tons) and has three totalizers.
In addition to the basic functions of dynamic weighers, the WE503D
also has Batch functionality and a PID control function, which can
be used to control the capacity in function of a setpoint.
Possible inputs and outputs are analogue (4-20 mA), Digital I/O (and
counting pulse), RS-232/RS-485, USB port, Modbus RTU, Ethernet
TCP/IP, Modbus TCP, Profibus-DP, Profinet, EthernetIP, CANOPEN
and other Fieldbus connections.
