Basically, scales and belt scales should only ever perform one task: Measuring the weight of something so that you can achieve equally accurate results with precise measurements.
But simple weight measurements are not always enough.
There are also important tasks where weight takes a back seat and volume plays a decisive role for you and your company.
Our belt scales focus on volume, not weight, for precise measurement.
Because if errors are possible here, then repeated measurements cost time and money that you can definitely invest better.
You may now be asking yourself: A scale that doesn't measure weight? What is that good for? We would like to give you an example of these scales.
An example of the immense advantage of an optical belt scale
Let's assume that someone wants to lay a heavy cable under a river. The resulting drilling material travels away from the construction site on a conveyor belt.
However, it is very important that the volume of the supported soil does not exceed a certain point:
The volume of this must not be greater than that of the drilled cylinder. Otherwise, work must be stopped immediately.
The operator of the drilling rig has therefore come up with the idea of using an ordinary conveyor belt scale for this application.
He then wants to convert the accumulated weight into volume using a correction factor. That sounds like a good idea at first.
But this is where it becomes problematic: this procedure requires a certain, sensitive ratio of soil density and loosening factor. If these two do not remain constant, the results are useless and all the work may be in vain.
Gravimetric errors therefore always depend on the accuracy of the bulk density input. These directly influence the measurement accuracy.
For this reason, we do not recommend gravimetric, i.e. mass-based, scales for such applications. Instead, you should use an optical conveyor belt scale.

This type of scale works in conjunction with a high-speed scanner. This scans the surface of the belt with optical sensors to determine the volume.
The machine uses a pulse power of 60 megawatts per laser (mW/laser) with a pulse duration of 400 µs.
Even high temperatures of up to 70°C are no problem for this optical conveyor belt scale, nor are low temperatures of up to -40°C.
So whether you are loading trucks in freezing Siberia or monitoring processes in the desert: The optical belt scale will not let you down.
Data always available thanks to the included smartphone and corresponding software
In addition to the scale, you also receive a robust CAT smartphone. This enables the rapid exchange of data and the display of flow rate and absolute volume.
However, you can also call up this important information in another form.
You can view the relevant information for the operator data, print it out and send it to a PC using a cable or via e-mail.
If you also use a SIM card, you can also send the information directly from your smartphone. Hense Wägetechnik offers you a wide range of options for forwarding this data.
For example, if you are unable to use a printer in your area, you can simply forward the read-out information to the responsible employees via e-mail.
Or if a non-digital solution is required, a clear print version on paper is also possible.
This ensures that a viewable copy of the document is available even if the battery is empty.
Data storage for the efficient use of your machine
So that you can access previous measurements and stored content, the optical belt scale also offers a measurement data memory of up to one year.
Are you also interested in a statistical analysis of your data? That's no problem either. You will receive special software that makes this possible free of charge.
This allows you to obtain detailed information about your results, which makes your work more efficient.
Optical belt scales: application examples and user data
But which specific examples are suitable for the use of such an optical belt scale?
As already mentioned in the example about the drilling measures, the optical belt scale has proven to be a decisive solution for bulk density problems.
However, material flows, loading truck loads or simply process monitoring are also made considerably easier by using a volume-based scale.
The height of the assembly should not exceed 950 mm. The layer height of the materials on the belt, on the other hand, can be up to 680 mm.
Say goodbye to frequent maintenance for your belt weigher
But no matter in which area you end up using the scale, maintenance of the machine will be kept to a minimum. This is because the optical belt scale consists of just three components:
A sensor head including integrated electronics, a holding device and the proximity initiator, which is responsible for measuring the speed.
As a result, there are no loose components that need to be monitored, maintained or checked. Regular maintenance is therefore not necessary.
At most, Hense Wägetechnik recommends a simple cleaning of the sensor from time to time in dusty environments.
However, this can be done in no time at all and requires no special knowledge.
Conclusion
If you value accurate and error-resistant results for your tasks and orders, then the optical belt scale from Hense Wägetechnik is your partner for an efficient solution.
Thanks to the optical-based measurement of volumes, there are no more disturbing measurement errors that are possible with gravimetric scales.
This means that even sensitive operations such as drilling under rivers, where the volume extracted is crucial, are no longer a problem.
The lack of loose or loosened components in the belt scale eliminates the need for frequent maintenance.
Only the sensors need to be cleaned of dust from time to time if the machine is used in a dusty environment.
But maintenance is not the only thing that is eliminated. Thanks to the high temperature resistance, you don't have to worry about the usability of the scale. From -40°C to +70°C, the machine runs without any problems.
Thanks to the robust CAT smartphone, you can access the data read from the scale at any time. This means you can forward it at any time by e-mail or send it to a printer, which provides a paper copy.
This data can also be retrieved and stored for up to one year. The large amount of information guarantees efficient work planning.
The free software supplied facilitates statistical analysis of the work results, which means that you not only have information at your disposal, but can also use it to precisely control your production.
