Tests are increasingly performed in the “real” world, often in harsh environmental conditions. This is particularly true for the prototype testing phase, which ensures that the vehicles can also be used in extreme weather conditions. To facilitate these tests, the measurement amplifier systems, too, must be able to withstand the extreme temperatures for ensuring extreme data security. This is also owing to the fact that such comprehensive tests cannot be repeated for efficiency and cost reasons. Therefore, the amplifier systems and memories must withstand cold weather, shocks, and vibrations.
HBM’s SomatXR is a measurement amplifier system that meets the efficiency requirements of cutting-edge test setups (including the web interface) and offers a high level of robustness. What does robustness actually mean? Firstly, the mechanical characteristics need to be considered: The modules have been designed for use in a temperature range from -40°C to +80°C. It is also possible to obtain measurements passing through the dew point because the modules are completely sealed so that there is no condensation inside. The SomatXR modules have the IP65/67 degrees of protection and are shock-proof up to 75 g (in accordance with the Military Standard 202G). These are only (a few) mechanical standards. The robustness in terms of software and data security is at least as important.
SomatXR CX23-R Data Recorder for Unattended Testing
The SomatXR CX23-R data recorder for unsupervised testing runs a stable operating system. The data format itself is also highly robust because it does not use any storage sequences. Even if data is still being uploaded to the recorder, the first part of the measurement can already be downloaded. Further, the web interface also ultimately provides safety. Data can be accessed from anywhere, irrespective of the number of users who access the data or the operating system they use.
SomatXR CX22B-R Data Recorder for Interactive Vehicle Tests
The SomatXR CX22B-R data recorder, on the other hand, has been specifically designed for interactive vehicle tests. The catman measurement software is pre-installed on the recorder and the data is stored in the .bin format. Converting it to other formats is easy as well. The CX22B-R acquires data from the SomatXR modules using an Ethernet connection. The FireWire simultaneously allows the data recorder to be used as a gateway for direct data transmission to the PC. Both centralized and distributed measurement systems can thus be implemented.
