Sensors

From tight bends when building roundabouts to long straights on trunk roads – the requirements on sensors for grade and slope control can vary enormously depending on the job in question. VÖGELE has a comprehensive range of sensors for this, encompassing a variety of mechanical and sonic sensors as well as the Big MultiPlex Ski sensor system. As a result, the right sensor is available for every paving application.

The NIVELTRONIC Plus and Basic products for Automated Grade and Slope Control from VÖGELE are unique systems providing the basis for efficient paving true to line and level on any kind of base. The high degree of accuracy during paving is achieved by combining automated grade and slope control with various sensor systems.

The key advantage of mechanical sensors is that they are not susceptible to external influences such as water, wind, sunlight, temperature fluctuations or air turbulence caused by passing traffic. An added bonus is that the point at which the reference is being scanned can be detected immediately. This makes it particularly easy to check whether the sensor is in stable contact with the reference. The point at which the reference is being scanned can accordingly be detected immediately.

VÖGELE supplies three different non-contacting acoustic sensor systems: the single-cell sonic sensor, the multi-cell sonic sensor and the Big MultiPlex Ski. The functional principle of all three acoustic sensors is identical: an acoustic signal is always emitted, reflected and received back.

In contrast to acoustic sensors, optical sensor systems use laser beams instead of sound. The great advantage of optical sensors is that measurements cannot be falsified by external influences such as wind or fluctuations in air density. A further benefit is the extensive range of the laser beams, permitting distances of up to 200 m between transmitter and receiver.

The use of 3D machine control systems in earthworks is already common practice, but now road pavers, too, are increasingly being equipped with this technology. For its SUPER pavers, VÖGELE delivers the right solution to tackle every application.
