Ideally suited for recording and capturing vibrations, shocks and impacts.
The accelerometers delivers ultra-low noise density over an extended frequency range and is optimal for e.g. bearing fault detection and diagnostics. The accelerometers has typical noise density of 26 μg/√Hz across the linear frequency range which provides the ReLog with extremely reliable resolution and accuracy. Microelectromechanical systems (MEMS) accelerometers have stable and repeatable sensitivity, and are immune to external shocks up to 10,000 g.
The ReLog features an aluminium casing to be able to achieve highest possible accuracy when sampling at high frequencies.
From experience, we know that you as a user probably already have quite a good idea of how to understand and interpret your data. In order to allow you to analyse the data in any way you want the ReLog will provide you with a .csv file containing all the accelerometer data captured.
Included with the ReLog are components that will allow you to mount the data logger by using screws, adhesive and magnets. For highest quality measurements we recommend using screws.
Battery life and memory
How long measurements you can do is depending on both battery life and memory. When sampling at high frequency, it is typically the memory that is the limiting factor, and this is why we have equipped the ReLog with and 32GB memory card, with the option of expanding it to 64GB. This will allow you to measure continuously for over 70 hours when sampling at 25,000 Hz in all 3 directions!
How do I define the settings?
The settings are defined and configured through a simple text file (“settings.txt”). This makes sure that the user can easily navigate through and get and overview of all configurations.
