Description

Technical field The present disclosure relates to a compressor, in particular a system for displaying a difference in the amplitude setting for the compressor and a method for displaying the difference in the amplitude setting for the compressor. State of the art A compactor is used to compact materials such as asphalt, soil, concrete, and/or other materials. The compactor comprises a pair of rollers that come into contact with the materials to be compacted. Specifically, the roller pair includes a first roller located at the front end of the compactor and a second roller located at the rear end. Each roller is equipped with a vibration system to vary the amplitude and frequency of its vibrations. In some cases, the compactor may be incorrectly adjusted, causing the rollers to operate with different vibration amplitudes. These differing vibration amplitudes between the first and second rollers can lead to poor and/or uneven compaction, negatively impacting compaction density. Furthermore, these differing vibration amplitudes can cause roller wear, damage to the rollers, and/or material loss. Additionally, the uneven vibrations, transmitted to the compactor's operator's cab, can increase operator fatigue and discomfort. WO2022079643 This describes a vibratory compaction machine comprising a chassis, at least one roller, and a control system. The at least one roller is rotatable about an axis oriented in the Y-axis direction and is mounted on the chassis to allow rotation of the roller over a work surface. The at least one vibration mechanism is configured to generate vibrations that are transmitted as shocks in the Z-axis direction from the at least one roller to the work surface. The at least one vibration mechanism is provided with a variety of different amplitude settings. The control system is configured to measure the acceleration forces of the at least one roller in a direction substantially corresponding to an X-axis direction, wherein the acceleration forces are generated by the vibration mechanism and the X-axis direction extends in a direction substantially orthogonal to both the Y-axis and the Z-axis directions.
