This Innovation Lab post covers how to measure vibrations using the A121 Radar Sensor Evaluation Kit. Vibration measurements can be utilized to predict maintenance need. For example, movement of constructions such as buildings and bridges, and structures such as train tracks are measured and maintained before these infrastructures are going to be damaged or collapse. Moreover, monitoring condition of industrial machinery can be useful for saving maintenance cost and prevent fault operation. Continuous measurement can be done without stopping machines. More information regarding vibration measurement can be found on the Acconeer document site.
You can explore vibration measurement with the A121 sensor using two different set-ups:
- Either using the Acconeer Exploration Tool desktop app, or
- Flash the C code example app in the SDK
The video below shows the A121 sensor estimating the frequency content of a vibrating object, measured at a distance.
In the Exploration Tool, click “Vibration measurement” on the left-side menu, and then click “Start measurement” on the right-side menu to start measuring vibrations.
