Sensors

From tight bends when building roundabouts to long straights on highways – the demands on sensors for grade and slope control can vary widely depending on the specific job. VÖGELE has a comprehensive range of sensors including a variety of mechanical and sonic sensors, as well as the Big MultiPlex Ski sensor system. So the right sensor is available for every paving application.

The VÖGELE NIVELTRONIC Plus and Basic are unique systems for automated grade and slope control 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. Another plus is that the point at which the reference is being scanned can be detected immediately. This makes it very easy to check that the sensor is in stable contact with the reference. So the point at which the reference is being scanned can 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 220 yards (200 m) between the transmitter and receiver.

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