Radiometric sensor for mass flow determination
Throughput measurement
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 WEIGHTRAC 31 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.
Your benefit
Exact determination of the delivery volume through simple setup
Wear-free, because non-contact measurement
WEIGHTRAC 31 is a mass flow measurement for precise bulk solids detection on conveyor belts and in screw conveyors. PVT is used as scintillation material.
