The Dynascale belt scale model Loadblock is very easy to handle and installed by simply 2 bolts, delivered if needed with installation brackets, 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 very compact design and robust construction keeps the Loadblock weighing frame fully in line with the conveyor frame. This one-piece or two-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 Loadblock weighing frame is due to its specific design 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 Loadblock belt weighing system weighs and counts within a value of +- 1% of the test value. Calibration should be done via a known test weight, calibration chain or our standard electronic calibration.
