Description

The impact scales of the ImpactWeigh series are used for continuous weighing of free-flowing and homogeneous bulk materials in vertical process routes. The weighing of bulk material takes place during the fall. The ImpactWeigh scale is developed and manufactured by MTS for flow rates from 5 up to 400 m³/h.

The impact scale is suitable for many tasks requiring the continuous quantity measurement of bulk materials in vertical process routes, e.g. recording of in-process material flows, inventory control or optimization of truck and wagon loading.

 

The scales of the ImpactWeigh series consist of a stable enclosure, the impact plate with a special mounting system and the measuring chamber. The separation of product and measuring chamber secures the weighing system and allows for the usage in dustproof and Ex zones (optional).

 

Furthermore, the ImpactWeigh can be equipped with a static testing device. So, the measurement accuracy can be checked easily and and quickly.

 

Besides this, there are special coatings (made of special plastics, ceramics or others materials) for the impact plate available. The coatings increase the wear protection of the impact plate and its gliding properties.

Functioning

The solids flow is conveyed with constant drop height through a feed chute 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 high precision strain gauge load cell in the measuring chamber transforms the deflection into an electrical signal which is scaled and displayed by the control unit.

 

Due to the special suspension mechanics, material deposits on the impact plate do not influence the zero-point stability of the scale. Only horizontal forces are transmitted into the measuring chamber.

 

The ImpactWeigh has to be integrated into a conveying system in such a way that a constant output speed of the bulk material is guaranteed. Elevators, screws or belt conveyors, vibration chutes or rotary feeders can be used to this effect.
