Vibration monitoring goal

Vibration monitoring is the process of measuring and recording vibration levels as well as comparing results to specified limits to take action when a vibration limit is exceeded. The goal of vibration monitoring is to keep the vibration levels from exceeding the limits and damaging the object being monitored. In many cases, construction vibration (e.g. from a pile driving) can cause costly repairs or downtime. By constantly monitoring construction vibration levels, engineers can address problems before they cause serious damage.

The vibration data from vibration monitoring is used for analysis to determine the cause of the problem. By understanding the root cause of the issue, future incidents with construction equipment can be prevented. There are several ways to do this, including using geophones or accelerometers. By monitoring vibrations, companies can take steps to reduce them when necessary, helping to protect both their workers and the surrounding area.
