Which sensors can be used to monitor the vibration frequency of the roller?

1. Acceleration sensor: used to monitor the vibration of the roller's steel wheel, and judge the density and compaction of the soil based on the changes in amplitude and frequency;
2. Pressure sensor: directly measures the pressure of the roller tire on the ground to determine the density of the soil;
3. Displacement sensor: such as magnetostrictive displacement sensor, installed on the shaft of the vibrating wheel, and feedback the position information of the vibrating wheel by measuring the displacement of the shaft, thereby indirectly monitoring the vibration frequency;
4. Vibration frequency detector: specially used to measure the working frequency of the vibrating roller.
