The KiDAU data acquisition system and KiBAT, the rugged special battery: a combination from Kistler that adds up to a universal system for efficient, successful measurements in crash tests – a major factor in vehicle safety.
During a crash test, several thousand sensors operate simultaneously to deliver reliable measurement data. The strong forces and accelerations that act during these tests demand measurement technology with high levels of efficiency, reliability and shock resistance. KiDAU – the new data acquisition system from the Kistler Group – is used in demanding conditions such as these. To complement the universal KiDAU technology, the rugged KiBAT battery management system is the key to guaranteed data protection.
Even the best data acquisition system is useless if measurements are interrupted during a crash test. To prevent this from happening, Kistler has developed KiBAT K3885 – an intelligent onboard battery. If the cabled power supply fails, the special battery from Kistler cuts in: it buffers all the onboard components via the CrashLink2 bus. This gives customers 400 Watts of power for a 10-minute period – so measurements can continue without interruption and the system captures reliable data. Five colored LEDs indicate status and if the energy level is low, KiBAT also emits an acoustic signal.
The case for KiBAT is very robust, making it ideal for demanding crash test applications. The battery can be switched on either automatically via the CrashLink2 bus, or manually – to ensure ease of handling in different application situations.
As an additional link in the onboard data acquisition chain, KiBAT ensures that the processes for preparing and conducting crash tests will run smoothly. Kistler draws on its extensive experience of safety system trials and tests in a wide variety of vehicles to continue improving safety for vehicles and traffic.
KiDAU Stationary K3880AS combines multiple measurement technologies in one 19-inch rack carrier with various plug-in modules that can be used with one another. Kistler developed this universal data acquisition system for use in preparing and certifying dummies, and also for component tests. Now, thanks to this innovation, the high performance and reliability standards of mobile onboard devices are also available in a stationary application for laboratory use.
The base unit includes integrated interfaces with the external crash test infrastructure. Existing onboard devices can be connected directly via four CL2 interfaces. The case for KiDAU is executed in the standard 19-inch design and is cooled without a fan. Modular architecture allows it to accommodate up to eight plug-in I/O modules. There is also a unit with 16 digital input channels that can save data in a cycle of 1,800 seconds with a sampling rate of 100 kHz – so recording can begin even before the test starts. And in addition, the KiDAU K3880AS features 8-channel plug-in cards for analogue inputs: each one is equipped with a programmable input amplifier, bridge excitation circuit, low-pass filter and a 16-bit analogue-to-digital converter. All settings can be made via software, either automatically or with commands. The extensive range of technical equipment makes this data acquisition system suitable for universal use – a straightforward, reliable solution that guarantees the availability of measurements on dummies and components.
