Avoiding overflow

If the infeed overflows in a system that processes plastic granulate, the drive can be damaged and the entire process may come to a standstill. The work and expense would be immense.
 
The Israeli electronics manufacturer Galoz electronics Ltd. therefore implemented a compact and highly integrative optical monitoring system for a global leader in the development and manufacture of high-quality additives, mixtures and coloured plastic granulates for the plastics processing industry whose products are used in injection moulding applications. These granulates form the basis for plastic parts in the automotive industry as well as for garden furniture and household appliances.
 
The task was to monitor the correct fill level of the granular raw material in the supply line to the shredder. Overfilling would damage the main drive and result in system downtime as well as immense repair costs. The company had not previously found a way to reliably and intelligently monitor the supply line.

Moreover, direct networking between the supply and discharge was lacking. In the case of a slower discharge, excessive fill levels and overflow in the supply channel occurred time and again. The raw material came into contact with the warm main drive motor and melted. As a result, material could penetrate the interior of the drive, which then failed. The responsible equipment supplier,

Galoz electronics Ltd, found a solution to this problem – with the LRS 36 light section sensor from Leuze electronic.
