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.
VibInspect
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.
