Optical Belt scale

Sensortechnik Optical Belt Scale is a contact free volumetric scanner. Using the latest laser technology, Sensortechnik effectively scans the material crossing the belt with a measurement accuracy of 1mm variance. Whether your conveyor is stationary or on tracked equipment, you can rely on the precise production data unaffected by external conditions. Beyond its practical measurement application, Sensortechnik Optical Belt Scale is truly an operations management tool.

ptical Belt Scale is the industry leading volumetric scanning technology, originating from Austria, where it has been the proven choice in Europe for over 20 years.

With dealers all over the globe, Optical Belt Scale is revolutionizing the way material measurement is handled, from aggregates to waste & recycling, or stationary conveyors to tracked equipment.

Featuring the accuracy, the longevity and data rich results which put you in control of your operations.

How does the optical belt Scale work?

The optical belt Scale records the volume flow on the conveyor belt without contact. The system is equipped with lasers. The number of lasers depends on the belt width.

The laser beams are directed to the surface of the conveyed goods and are reflected back by them. A photo diode detects the reflected laser beams.

The change in the angle of incidence is used to calculate the distance of the conveyed medium from the belt surface and from this the layer height is calculated by triangulation.

The large number of sensors makes it possible to take exact optical measurements of the material profile on the belt. As with a conventional, gravimetric belt scales the speed of the conveyor belt is determined by means of an inductive sensor.

The sensor calculates the actual volume flow from by multiplying the speed of the belt and the cross-section profile detected in high resolution. The calculated volume flow is integrated by the electronic system and is saved as the absolute transported volume.

Different bulk densities can be stored inside the electronics for a variety of products. For this reason, the volume flow (m³/h) for every product can be individually converted into a mass flow.

The collected data are saved in the sensor’s electronics for up to one year. Access is possible via a Bluetooth connection or serial interface.

Bluetooth and a robust mobile phone with specialised software are used to adjust and calibrate the belt scale. In this way, the data can be forwarded and processed by e-mail, Bluetooth or by an USB cable.

For stationary applications there is an analogue output (4 – 20 mA) to transmit the current flow and an impulse output to transmit the absolute volume.
