Radiometric sensor VEGA WT31

Type WT31

Radiometric sensor for mass flow determination


Application Area

The frame construction offers a simple mounting option for a retrofit on a conveyor belt, to enable non-contact throughput measurement of bulk solids.
The radiometric sensor for mass flow determination VEGA  WT31 is a radiation-based sensor for precise flow measurement of bulk solids. It is ideal for mass flow determination on conveyor belts and in conveyor spirals in all industries. Due to its frame construction, the WEIGHTRAC 31 can be simply retrofitted to the conveyor belt.
