Case Study: Siemens Mobility

Siemens Mobility optimizes vibration measurements on rail vehicles with the microUniDAQ from D.SignT

Initial Situation

In the railway sector, there is a recurring need to test vehicles under real operating conditions. Conventional measurement systems are often bulky, require complex cabling, and are therefore time-consuming to install. A solution was required that would be flexible, compact and cost-effective, especially for temporary measurements with a limited number of channels at hard-to-reach locations.

Innovative Solution with the D.SignT Data Logger

The microUniDAQ data logger from D.SignT, when used in conjunction with appropriate sensors, has been shown to be the ideal solution to these requirements. Its compact design facilitates rapid and efficient data collection.

Benefits

• High flexibility: The system's expansion with a battery pack allows for autonomous data acquisition operation.
• Ease of use: The installation process is efficient and straightforward. The compact measurement system can be installed and removed quickly and conveniently using a mounting fixture.
• Intelligent triggering: The data collection process is initiated by level threshold detection, thus ensuring that only relevant data is recorded.
• Cost efficiency: This system requires significantly lower investments than conventional measurement systems.

Conclusion and Outlook

In practice, the microUniDAQ has proven to be a robust and user-friendly plug-and-play solution for mobile vibration measurements on rail vehicles. Its compact form factor, fast installation, and autonomous operation enable efficient temporary measurements, even in hard-to-access locations.

Planned firmware enhancements, including on-board data analysis will further expand the system's functionality without requiring hardware changes. In response to customer feedback, future device variants will incorporate ingress protection against dust and water.
