Acceleration logger
An acceleration logger is a measuring device that autonomously records shocks or vibrations over a certain period of time. The shock and vibration data can be called up, viewed and evaluated after recording.
function
An acceleration logger consists of acceleration sensors , a storage medium, processor and a power supply. The sensors measure data, i.e. shocks or vibrations. The processor processes the measurement data and saves them with the associated measurement times on the storage medium. This allows the measurement data to be called up after the measurement, either directly on the logger or via an interface on a computer. Software displays the measurement data in tables or diagrams and offers functions to evaluate the measurement data. A common evaluation method is the acceleration-time diagram with DBC .
The shock and vibration data are recorded either continuously over a defined period of time or based on events that meet certain criteria. An event-based measurement can be used to specifically record impacts that exceed a critical duration or strength.
Acceleration loggers use non-volatile storage media to store the measurement data. These are, for example, hard disks or EEPROMs . You don't need electricity to store your data. Therefore, the measurement data are retained even if the power supply fails.

Acceleration loggers are used, among other things, to:
- To monitor sensitive and valuable goods during transport or in warehouse handling.
- To measure accelerations in motor vehicles, for example for the reconstruction of traffic accidents.
- To monitor machines in productive use that are sensitive to shocks or vibrations.
- Determine the stresses and strains on people when riding roller coasters.
- Determine accelerations for objects on conveyor belts.
Transport monitoring
Acceleration loggers can monitor the transport of sensitive and dangerous goods. For this purpose, they are firmly connected to the goods during transport and record impacts or vibrations. The measurement data reveal whether the transported goods were exposed to a risk of damage or when and what caused damage. In addition, transport routes, means of transport and transport packaging can be optimized based on the measurement data.
The European standard EN 15433-6 exists for acceleration loggers in transport monitoring. Standard-compliant loggers guarantee defined functions, usability and safety.
