A new universal measuring system from Kistler is providing reliable measurements for crash tests with no interruptions.
During a crash test several thousand sensors need to operate simultaneously under challenging conditions involving strong forces and accelerations. Kistler’s new system combines the KiDAU data acquisition system with the KiBAT battery management system to provide high levels of efficiency, reliability and shock resistance.
The KiBAT K3885 cuts in if the cabled power supply fails providing 400W of power for a ten minute period buffering all onboard components via the CrashLink2 bus. This ensures that measurements continue without interruption.
The KiDAU Stationary K3880AS combines multiple measurement technologies in a single 19’’ rack carrier with up to eight plug-in modules. The base unit includes integrated interfaces with the external crash test infrastructure and existing devices can be connected directly via the four CL2 interfaces.
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 100kHz, so recording can begin before the test starts. All settings can be made via software, either automatically or on command.
