Sensors and scanning equipment

The sensors

Deviations from the target value are picked up by the sensors and calculated by the levelling system, which then automatically transmits a corrective value to the machine. Different sensors are used for different applications depending on the reference used (e.g. pavement surface, kerb or stringline).

The sensors are generally available for all product divisions and machine types and are used to suit the specific application.

Cable sensor

A mechanical cable sensor connected to the side plate with a wire determines the difference between the side plate and machine chassis.

Hydraulic cylinder sensor

Path sensors in the hydraulic cylinder determine the difference between the side plate and machine chassis.

Ultrasonic sensor

The non-contact ultrasonic sensor determines the distance of the machine to the reference surface.

Slope sensor

The level sensor is used to determine the absolute difference to the gravitation force reference.

Sonic Ski sensor

The non-contact Sonic Ski sensor determines the distance of the machine to the reference surface. This may also be a stringline.

Multiplex systems

Multiplex systems combine multiple sensors on one or both machine sides (e.g. cable, ultrasonic, cylinder sensor). Using the average value of the connected sensors, the current milling depth is calculated with high precision.

Laser sensor

With laser levelling methods, laser sensors on the machine receive signals from a rotating laser beam.

3D sensor

A total station focuses a receiver prism, from which it calculates the position and height of the cold milling machine. This data is transferred to the 3D computer for further processing.
