Building, Cement & Quarry
In aggregate, quarry and mining applications, the conditions are often extremely noisy and dusty. UWT offers robust sensors with total reliability as standard - whether for mobile plastering machines, mixing systems with heavy vibrating conditions, volume measurements within dosing tanks, stone crushers, conveyors or cement storage silos.
The Challenge
A plant builder in Estonia asked for a level switch in a gravel hopper. The function should be a demand detector to set an alarm in time if the hopper gets empty and more material should be filled in. The hopper is equiped with an electrical rotary vibrator. It is mounted at the cone wall. It avoids material deposit the the wall inside and improve the material flow. The vibrator works in short bursts. The hopper is top loaded with a front loader. The material is gravel with 0-32mm grain size. The hopper is located outside therefore the sensor must have a temperature working range from -20 to +30C.
The challenge for the sensor is the strong mechanical load to the electronic housing by the vibrator and to the extension probe inside the hopper by the gravel.
Our Solution
The solution was a rotating paddle switch Rotonivo RN3004 with the option for a separate housing. It is mechanically uncoupled to the process. A rubber plate devides the shaft and damps the swinging amplitude and protects the gear and the electronic parts against damage. The protection tube at the probe protects in the application. So the gravel cannot damage the sensor and cause a malfunction. The solution is simply working and solves this heavy application.

The Challenge
A customer in England manufactures stone recovery plants for the quarrying industry. The stones are placed in a container filled with water, which is stirred slowly. All the dirt is removed from the stones. The stones are then sold again as building material. The dirt in the water settles as mud at the bottom of the tank.
The application requires the measurement of the sludge level at the bottom of the tank. From a certain height, the mud is pumped out.
The customer had already tried a radar and an ultrasonic system, but both were unsuccessful due to the high solids content in the water and the movement of the water.
Our Solution
The Nivobob NB3300 was used and proved to be a successful product for this application. The advantages that the Nivobob has over other technologies used are as follows. The sensing weight is not affected by the water movement. It moves through the water surface to the mud layer and feels like the separating layer. The sensing weight of the sensor can be adjusted to the viscosity of the slurry. An electromechanical, reliable and easy-to-use system for measuring the sludge level in the wash tank.

We were contacted by a long standing client regarding successful continuous level measurement in for their process hopper. The application revolved along a train tippler that tips the contents of the train truck (in this case, coal) into the hopper below which is then conveyed to the site. The issue they were facing is that their existing radar units from a competitor supplier did not meet their highly accurate demands and could not cope in the environment.
Our Solution
Due to the nature of the application, the NivoBob could not be used. We offered the NivoRadar with a dust tube fitted with air purge to keep the dust off the lens. The radar was installed on a beam that was hanging over the bulk of the coal. After 2 weeks of successful testing, the client had bought 2 more units for this application. The dusty environment was successfully overcome by the dust tube with and airline connected to purge the lens. Accurate and repeatable reliable readings meant a successful solution to this difficult application.
