Can be perfectly used with the control unit ModWeigh PPW.
The ImpactWeigh series of impact scales are used for continuous weighing of free-flowing and homogeneous bulk materials in vertical process flow. The material is measured during its fall. The scales are developed and manufactured in-house. They are available in several sizes for flow rated from 5 to 600 m³/h.
The ImpactWeigh is suitable for numerous tasks. It records the material quantity within a closed conveyor system in vertical process flow, for example for:
• Recording of internal material flows,
• Inventory control or
• Optimization of truck or wagon loading.
The impact scales consist of three parts: a stable housing that serves as a product chamber, an impact plate with a special mounting system, and a measuring chamber. The product chamber and the measuring chamber are separated from each other. This ensures that the weighing system is well protected. Optional use in dustproof and Ex zones is also possible.
The impact scale has a compact design and a low installation height. The simple mechanical design allows for quick installation. The measuring chamber of the scale can be opened from the outside. This makes repairs much easier and faster.
A static testing device is available as an option. This allows the user to quickly and easily check the accuracy of the impact scale. Two test weights and a special mounting system are required for this. This allows the adjustment value to be compared with the measured value.
On request, the impact plate can also be coated with various materials for wear protection. A ceramic coating, for example, offers very high abrasion protection.
The solids flow is conveyed with constant drop height through an inlet to the inclined impact plate.
According to the formula:
Force = Mass x Acceleration
the product flow rate produces a constant force impulse upon the impact plate and a horizontal deflection.
The horizontal force of the impact impulse is converted into an electrical signal by a high-precision strain gauge load cell. The control unit standardize this signal and display it.
Due to the special suspension of the impact plate, material deposits have no influence on the zero-point stability of the impact scales. Only horizontal forces are transmitted.
The ImpactWeigh impact scale must always be installed in the conveyor system in such a way that a uniform discharge speed of the bulk material is ensured. Suitable conveyor types are screw conveyors, rotary valves, bucket elevators, vibrating chutes, conveyor belts, or scraper chain conveyors.
