Unsure which ReLog is the one for you?

Let our expert sales engineers guide help you by walking you through the products and which ReLog will suit your application the best. We are always happy to discuss measuring vibrations, demonstrating the ReLog and showing how VibInspect can help you visualise and analyse the vibration measurements. Use the button below to get in touch with us and schedule your session. 

Application areas for the ReLog

Vibration monitoring

Monitor vibrations in your environments with high accuracy and precision. Ensure that high quality data is captured and analyse it correctly with our free software

Failure mode analysis

The ReLog can efficiently be used to discover and analyse unexpected vibration patterns and provide basis for explanations why products fail unexpectedly.

Transportation monitoring

Monitor your cargo or vehicles by attaching the ReLog to an area where vibrations are likely to occur and could be an indicator of damage

Precision measurements

The ReLog is perfectly suited for sophisticated testing institutes that wish to conduct high precision measurements without using cables and wires to set up the accelerometer

Product evaluation

Measure vibrations with the ReLog to understand how your product is performing during the development stage and ensure that all potential failure modes are detected

Shock monitoring

Use the ReLog to monitor if your products or assets are being exposed to shocks that could potentially be dangerous for the equipment itself.

Condition monitoring

Use the ReLog to monitor a system, asset or vehicle in semi-real time to detect failure modes and use the data to predict the failures before they occur.

Machine health monitoring

Similar to condition monitoring but rather use the ReLog on several different machines and occasion to ensure that the machines are in good health.


Vibration analysing software

To ensure you are able to analyse and interpret the data you’ve just acquired, each ReLog comes with an included software that allows you to perform analyses on the vibration or to convert the measurement data to a file format you can use in your own system.
