DYNASCALE BELT SCALE MODEL 1020
The Dynascale belt weighing system model 1020 measures, among other things, feed to crushers, mill, sieves and other processes with accuracies as low as 0.5%, in the most difficult conditions. The Dynascale process belt scale model 1020 allows you to monitor and control your production while providing information on efficient operations.
The Dynascale belt weighing system model 1020 is designed for process belt weighing in the most complex industrial applications. It allows you to control the supply to your system while providing important information for efficient operations. The Dynascale 1020 belt weigher has the proven reliability of the 1020 weighing frame, together with the 526 speed sensor and the power ofversatility of the advanced WI301 weighing electronics. The system is also available in approved version.
Features and installation
The Dynascale belt scale model 1020 is easy to install, indoors or outdoors, on stationary or mobile belts. Its robust construction makes it suitable for the most difficult applications on a wide variety of applications.
The weighing frame
Its sleek and robust construction keeps the 1020 weighing framefully in line with the conveyor frame. This one-piece weighing frame is fully assembled at the factory and is quick and easy to install and integrate into the conveyor belt. The weighing frame is designed to provide additional support and reinforcement to the belt structure, thus minimising deviations.
The weigh frame 1020 offers three-point support by using 1 loadcell and 2 low-friction closed pivot points. These are insensitive to vibration, moisture and product accumulation, unlike many other systems.
The belt speed sensor
The WIS526 digital speed transducer is the most reliable and accurate speed transducer ever developed for use with belt weighers. By directly connecting the transducer to the belt reversing roller or a return roller, you are guaranteed an accurate belt run reading. No wheels running over the belt, preventing problems caused by product accumulation or belt slip.
The Integrator
The WI301 integrator is a weight integrator for dynamic weighing systems. By integrating the mV signal from the load cells in the weighing frame and the pulse signal from the speed sensor, the WI301 integrator generates a readout for the product flow in e.g. tonnes/hour. It is also possible to read out the belt load (kg/m), belt speed (m/s) and the daily counter or total counter (kg or Ton). The integrator can also be equipped with various optional boards for e.g. communication purposes. The integrator can be used for both approved and non-approved applications.
Accuracy guarantee
On installations approved by us, we guarantee that the 1020 belt weighing system weighs and counts within a value of +-0.5 % of the test value. Calibration should be done via a known test weight, calibration chain or our standard electronic calibration.
If you want even better accuracies, we recommend switching to Dynascale model 1014.
