SICK extends LMS bulkscan non-contact belt measurement to more users

SICK has extended its LMS Bulkscan laser scanner offering, so that more users can benefit from non-contact, continuous measurement of volume and mass throughput of bulk materials on conveyor belts.

The SICK LMS111 Bulkscan provides highly-accurate, delay-free volume, and mass flow measurements to maximise throughput of a wide range of bulk materials including fertilisers, waste, crops, building materials, and food ingredients. Compact, and easy-to-integrate, the LMS111 Bulkscan can be designed into new lines or easily retrofitted onto existing conveyors.

The SICK LMS111 Bulkscan is a cost-effective alternative to a conventional beltweigher that offers the wear-free, low-maintenance advantages of non-contact, real-time measurement. The multi-echo, time-of-flight laser scanning technology enables a reliable output of the material’s volume and mass flow. In addition, the material’s centre of gravity is continuously monitored to help avoid uneven loading and resulting belt wear.

“The new SICK LMS111 Bulkscan presents a value-added alternative to a standard belt scale and is a robust and consistent performer even in dusty production environments or when mounted behind glass,” explains Darren Pratt SICK UK’s National Product Manager for Industrial Instrumentation.

“By measuring the load height profile every 20 milliseconds, the LMS111 Bulkscan delivers an accurate, continuous profile measurement. It then works out the volume of the material using the belt speed which can be provided as a fixed value or input via an encoder in the case of a variable speed belt. The mass is computed from the volume and a known density of the material.

“Volume is more important than mass for many production processes, making Bulkscan an ideal alternative to beltweighers in conditions where the density of material changes significantly. Asymmetrical belt filling or unequal bulk distribution can cause off-track running. The load height and centre of gravity also have important wear, energy efficiency, and safety implications in bulk conveying. As it’s non-contact, there is nothing to wear out with the LMS Bulkscan and it remains accurate without the regular recalibration needed for conventional scales.”
