• Perfect solutions

    for the building, cement and quarry sector

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

Our customer needed to measure the sludge level in a lamellar separator. The contaminated water comes from a large metal recycling plant, and the sludge level measurement is used to control a pump, which pumps the sludge into a press.

Our solution

In this particularly difficult application, the UWT VIBRANIVO VN1000 vibrating fork with a specially developed electronic module for interface measurement is the solution. The adjustable sensitivity means the sensor can be set to the required switch point. The VN1000 offers total maintenance-free functionality and has also been well proven in other interface applications. The excellent cost-/performance ratio is another plus in comparison with other measurement principles.

Products

With the following products our customer has solved this measurement task optimally:

NB 3300 Rope Version

Interface Measurement

  • Suitable for the continuous level measurement of sludges and solids in liquids.
  • Continuously reliable measurement results.
  • Flange mounting.
  • Measuring range up to 30m.
  • Version with improved corrosion resistance for chemical and salt applications.
  • Sensitivity adaptable depending on sediment density.

The challenge

Our customer is part of a major, well known worldwide corporation. In Russia, Ukraine and Uzbekistan alone the corporation has 16 cement plants as well as mixing plants and quarries. As part of a capital reinvestment programme, our customer requested level control technology for their vessels containing hot material which is processed from the cement mill.

Our solution

By installing the UWT rotating paddle switch ROTONIVO® RN3000 in this application, the solution is found – even at a process temperature from +250° up to +600°C. The robust and reliable unit is maintenance-free and fulfills the claim of “Install and Forget”.

The challenge

Our customer needed to measure the fill level in a mixing facility for building material. The particular challenge here was the extreme vibration at the facility and the very dusty environment.

Our solution

UWTs vibrating fork probe VIBRANIVO VN2000 meets these extreme measurement requirements. Its extremely robust stainless steel extension arm and the specially sealed electronics unit ensure constantly reliable measurement, even in such difficult applications.

Products

With the following products our customer has solved this measurement task optimally:

The challenge

Our customer required continuous level measurement in a cement and building material plant with 15 silos. The particular challenge was to guarantee reliable measurement in a dusty environment whilst ensuring easy operational setup. A test unit has been installed to replace radar and 5 units have been subsequently purchased.

Our solution

The UWT lot NB3200 fulfills these requirements. The sure to function high-tech lot offers a high measurement accuracy even under very dusty conditions and does not adversely affect the material characteristics. The NB3200 is mounted and after easy programming, is ready for operational usage.

Products

With the following products our customer has solved this measurement task optimally:

NB 3200 Tape Version

Continuous Level Measurement

  • Suitable for use in most bulk materials.
  • Integrated tape cleaner to remove aherent materials.
  • Mounting with threaded or flange connection.
  • Measuring range up to 50m.
  • Convenient level monitoring via Modbus interface together with cost competitive Nivotec 3500/4500.

The challenge

Our customer has a plant in Russia where insulation material is made from cellulose. Therefore, they requested an efficient and successful solution for limit detection. The problem within this application is the sticky material and the disposition to deposit build-up. Above all, the customer needed a fast reaction time by the switch for the low density (35g/l) of the material.

Our solution

The rotating paddle switch ROTONIVO® RN3001 with short extension is the best solution for this application. The installation of the unit can be vertical, horizontal or oblique in the silo. The unit is already suitable for material with a density of 15g/l. As a result, the RN3001 always promises precise and reliable full and empty detection

Products

With the following products our customer has solved this measurement task optimally:

RN 3001

Full, demand, empty detector
Short version

  • Vertical, horizontal and oblique installation.
  • Compact boom length, from 70mm.
  • Particularly suitable for small process vessels.

The challenge

Our customer from Belarus needed a device for several vessels that contain sand and slaked lime (mixture of sand and chalk) before they are further conveyed for mixing. Plus, the level of the final brick mixture needed to be detected in the subsquent vessels before the mixture is conveyed in a press.

Our solution

The level of the sand slake lime mixture is detected suing the vibrating fork probe VIBRANIVO® VN4030. The positive cost-/performance ratio of the sensor is perfectly suited for the detection of fine-grained sand. The level of the final brick mixture is detected using the ROTONIVO® RN3004 rotating paddle switches. The sensors have impressed customers around the world due to their long lifetime and complete reliability proven in thousands of applications over many years

Products

With the following products our customer has solved this measurement task optimally:

VN 4030

Full, Demand, Empty Detector
Tube extension version

  • Vertical, horizontal and oblique installation.
  • Cost competitive level detector.
  • Able to withstand high mechanical loads due to short extension length.
  • Shaft length up to 4000mm available.
  • Flexible height adjustment.

The challange

A plant operator in Russia requested the full detection in a pneumatic conveying system. The system conveys cement and quartz sand. The process pressure is 8 bar. The sensor needed to be loadably as well as fast and reliably switching

Our solution

The vibrating sensor VIBRANIVO VN4020 offers a perfect cost-/performance ratio and best technical attributes. It works at a process pressure of up to 10 bar and has the necessary mechanical stability due to its stainless steel Extension.

Products

With the following products our customer has solved this measurement task optimally:

VN 4020

Full, Demand, Empty Detector
Short version

  • Vertical, horizontal and oblique installation.
  • Cost competitive detector.
  • Compact extension length: 170mm.
  • Ideal for small process vessels and large silos.
  • Able to withstand high mechanical loads due to short extension length.

The challenge

Our customer, a soil processing company, required a low level detection probe for all dosing tanks, filled with several varieties of soil. Performance was supposed to take place regardless of material properties such as caking and high mechanical exposure.

Our solution

With the UWT level limit sensor of the capacitive series RF3200 this low level detector solved the problem in an excellent way. Due to the simple construction of the capacitive sensor and its reliability, an optimum outcome could be achieved. The first setting via “push button“ calibration is very easy to accomplish. High mechanical exposure does not effect reliable measurement.

The challenge

A manufacturer of building materials, who operates throughout Germany required an indicator for his Rotopack. This device (Rotopack) permanently filled bags (e.g. cement). Therefore a high reliability at the level switch was mandatory. Furthermore product changes were not supposed to affect measurement.

Our solution

With the UWT level limit sensor of the capacitive series RF3100 this application could be solved in an excellent way. Due to the high quality capacitive sensor, secure filling is guaranteed. The first setting via “push button“ calibration is very easy to accomplish. A product change does not affect reliable switching.
