Level measurement in different plastic granulars

The Challenge

For a manufacturer of plastic parts a reliable overfilling protection and a content measurement system for storage silos was required. The solid is HDPE-, LDPE-, PP-, PET- granular. The silos are in standard aluminum with 3 m diameter and a height of about 15 m. The applications are in atmospheric conditions, clean and without special requirements to the sensors. The only challenge could be the low DK-value.

Our Solution

In this applications the rotation paddle switch RN 3002 with tube extension will be used as a overfilling protection. For the content measurement the NivoBob NB 3100 is the right solution. Both sensors can be used in all plastic granulars. They are standards in synthetic applications and fulfill durable the tasks.
