For auger drives, proportional control is provided. When working in automatic mode, speeds of augers are precisely controlled to match the current laydown rate.

The level of mix is picked up as standard by mechanical sensors.

> Sensors for augers are located in the auger tunnel at the extreme ends of the screed.

> Actual values picked up by the sensors are passed on continuously to regulate auger drives.

> Proportional control is provided for the separate drives (left and right sides), i.e. speeds of augers adapt automatically to the actual levels of mix.

> This ensures uniform spreading of the mix in front of the screed.

> The use of sensors is easy on your drives and economical.

For pick-up of actual values, ultrasonic sensors are available as an option:

> Level of mix picked up more accurately by ultrasonic technology.> Ultrasonic sensors are immune to wear since they are operated contact-free.
