Abstract
A device for compacting the soil comprising a soil contact element which is impinged upon by an oscillation exciter enabling the soil to be compacted. The soil contact element is elastically coupled to an upper mass. The upper mass is used as a detection mass, whereby the acceleration thereof is detected by an acceleration sensor. A measuring signal emitted by the acceleration sensor is evaluated in a control device which controls the oscillation exciter according to a deviation from a set value.
