In-process control system for net weight of products dosed in hard gelatine capsules

The NETT system represents the most recent and important development in weight control systems.

The NETT system controls each filled capsule and eliminates from production any capsules which are outside the weight limits.

During normal machine functioning the NETT system, using two capacitive sensors, first checks the empty capsule and subsequently the same capsule after filling and calculates the net weight of the product dosed by subtracting one from the other. The two sensors are calibrated by an analytical balance. The system computer checks and manages all the data collected by the sensors and the balance and automatically deals with any weight adjustments.
