New UMC4013 operating unit
UMC4013 MMI

UMC4013 MMI

News 10-2017

We have listened to you and improved our operating panel of UMC4000 automatic dozer blade control: Instead of mechanical toggle switches to set several functions of the blade – such as offset on-grade, Auto/Man, slope side selection – we have built in a heavy-duty and easy-to-clean membrane keyboard. Now you must not recall how to move the toggle switches: Up/Down or Left/Right. A push on a button will activate the desired functionality.

There are two heavy-duty toggle switches underneath the joystick to open or close hydraulic side doors of the blade. You can find and operate them without looking to the panel.

In addition, we have added Russian language in the operating menu of the MMI. Thus, you can select now from six different European languages: German, English, Dutch, Italian, Polish, Russian.

Last but not least the operation of UMC4013 is now even more simple, more direct and logical. The automatic side-door open and close function can easily be activated by a push on the buttons “SSL” for the left side, and “SSR” for the right side.
The “SET” key buttons activate or regulate different sensor functions. As our control unit automatically scans and recognizes the connected sensors during initialization, the “SET” key buttons will activate only those function related to the corresponding sensors. Our UMC4000 system works proactively. The operation becomes simple and intuitive.

Multi-sonic sensor VA224 for Voegele Niveltronic
Ultraschallsensor VA224

VA224 Multi-Sonic Sensor

News 08-2017

The multi-sonic sensor VA224 is a new variation of the proven G224 multi-sonic sensor of the Danish company TF Technologies A/S. The VA224 comes with an analogue output signal and can be directly connected to the existing cable of Niveltronic screed levelling system of Voegele pavers. Thus, it can be used as a spare or replacement sensor of ultra-sonic skis of other manufacturers.

By means of the multiplexing method, the four ultra-sonic transducers of VA224 determine the height over a string-line or a reference underground. The mean value of the four individual measurements will be permanently sent to the Niveltronic controller to adjust the paver’s tow arms to level. The asphalt is laid down with the set thickness and smoothness.

Our VA224 multi-sonic sensor costs 2.180 € net (recommended retail price) going easy on your investment budget.

Please note that the VA224 cannot be used in a multiplex application (3 or more sensors on an averaging beam).

MatManager: Paving data monitoring
Planierschildsteuerung

MatManager

News 05-2017

Our MatManager is an all-in-one 7” display, central PC and operating panel. It monitors essential data of asphalt laying, stores them and create reports. The crew can see in real time how much material is laid down, and compare it to the target values. MatManager keeps track of the paving speed, distance and variable screed width und uses this data for calculations. At the same time MatManager measures and memorizes the asphalt material temperature and the weather conditions during the job.

Don’t lose time for calculations of material consumption! Our MatManager provides you an overview of actual and accumulated consumption. The PC shows you how much material is still needed, and when the next truck payloads shall arrive to your construction site.

The operator’s screen language of MatManager is available in German and English.

Mono-Sonic versus Multi-Sonic sensor
Ultrasonic detectors G221 and G224

Ultrasonic sensors G221 and G224

P.S. The sensor mounted to the back of an averaging beam is often placed over the hot asphalt mat. Of course, this can be done with the mono-sonic sensor G221 too, and it will work perfectly.

When planning for a new levelling system we recommend to purchase the Mini-Line basic kit consisting of HR301 controller and multi-sonic sensor G224. This way you are ready for all job conditions, no matter whether there is a reference string-line or curb-stone or levelled underground. Add now or later the Extension kit of Compact or Super Averaging beam with 3 additional mono-sonic sensors G221. Be sure, you have now a truly complete set of the best levelling tools for your paver.

News 04-2017

To meet virtually all paving job demands we supply both mono-sonic and multi-sonic sensors. The multi-sonic sensor has four transducers in a line. It can be used for distance measurements to even underground, curb stone and string-line. The mono-sonic sensor, however, will not work over a string-line.

Nevertheless, in a set-up of an averaging beam you may use mono-sonic sensors getting the same quality of asphalt road laying as having multi-sonic sensors instead. No quality loss, but mono-sonic sensors will save saving your budget.

To understand the reason for it let’s have a look to the working principle of ultrasonic sensors. In the beginning of the measuring cycle the transducer sends out an acoustical signal. After the signal has met the ground, it will be reflected and the sensor listens the echo. The time span between sending and receiving the signal is a proportion of distance or elevation of the ultra-sonic sensor above the ground. For a typical set-up at a paver the time between sending and receiving is 20 to 30 ms.

With a multi-sonic sensor (or ultra-sonic ski, or multiplex ski) every transducer will send out the acoustical signal and receive the echo one after the other only. Otherwise, the transducers would disturb each other. They would receive a false echo, and send wrong height signals to the controller. Moreover, the multi-sonic sensor has an integrated averaging function that is of benefit when working as stand-alone unit. It will throw away the maximum and minimum values and make an average of the two remaining results. Thus, a multi-sonic sensor will send less values to the controller than a mono-sonic sensor in the same time frame, but it will be a mean value for the length of the ski of 25 cm.

Having three or more sonic-sensors mounted on an averaging beam the controller itself will calculate the mean value before sending it to the tow arm valves of the paver. The averaging advantage of a multi-sonic sensor disappears in a beam set-up. Mono-Sonic sensors will send even more signals for averaging to the controller. Thus, you can thoroughly rely on mono-sonic sensors when you mount and use them on a Compact or Super Averaging beam.

No matter if mono- or multi-sonic sensors are in use the result will be the same: Uneven ground will be smoothed out over the length of the levelling beams, the resulting asphalt mat becomes more even.
