CHESTER
Scale

In many cases, weighing a container is the easiest way to determine its fullness, whether it contains liquids, gases, or even plastic granules.
CHESTER Scale can help you with this measurement. CHESTER Scale offers up to 10 scales connected to one unit. Each scale module can use a different range. This means you can measure 0-50 kg with the first scale and 500-1000 kg with the second one.
It uses the HARDWARIO Probe, a unique motherboard of its own design.

Typical use cases

In plastics production, conveyors are often used for granulation, where the granulate is transferred through a pipe directly from the hopper. In this case, a scale can be placed under the hopper and monitored to see precisely how the material in the hopper is decreasing.

In production, it is also possible to weigh crates of products or entire pallets. This makes it possible to identify whether all products are on the pallet or if any are missing. Thanks to continuous measurement, predicting when the pallet is full and needs to be replaced with an empty one is possible. For example, this method is also used when packaging various products with many smaller components.

Another use of the HARDWARIO CHESTER Scale is weighing gas cylinders. Even if the cylinder is heavy, regular measurements can show differences in filling loss. This makes it possible to predict when the cylinder will be empty and must be replaced.
