Vegapuls 68 Radar for Bulk Solids

A Tough Instrument for Tough Environments

Level measurement of bulk solids

Bulk solids, which vary widely in their density, form and features, confront the measuring instruments in industrial production processes with widely different challenges: powders often generate huge clouds of dust, while coarse, heavy bulk solids cause tremors and noise when being filled into a container from a great height. With VEGAPULS 68, level measurement in bulk solids is largely independent of process conditions. Due to optimized VEGA radar technology, the sensor can evaluate signals 1,000 times smaller than those conventional radar instruments can pick up. This high sensitivity allows a measuring range of up to 75 m even in products with bad reflective properties.

Operating Principle:

Radar

Features:

Non-contact measurement
High plant availability, because wear and maintenance-free
Reliable measurement independent of vapour, dust and noise

Application:

VEGAPULS 68 is the level measuring transducer for extreme bulk solids applications in silos of all kinds. Continuous monitoring of bulk solids with VEGAPULS 68 is largely independent of process conditions such as high temperatures or dusty environment, e.g. in coal handling systems in power plants or in storage facilities for building materials such as clinker or cement.
