Kistler Group has developed KiDAU, a data acquisition system for crash tests.
The KiDAU Stationary K3880AS combines measurement technologies in a 19in rack carrier with plug-in modules.
It was developed for use in preparing and certifying dummies and component tests.
The base unit includes integrated interfaces with the external crash test infrastructure and existing onboard devices can be connected directly via four CL2 interfaces.
The case is cooled without a fan and can accommodate up to eight plug-in I/O modules.
A unit with 16 digital input channels to save data in a cycle of 1,800 seconds with a sampling rate of 100kHz is available.
The KiDAU K3880AS has eight-channel plug-in cards for analog inputs equipped with a programmable input amplifier, bridge excitation circuit, low-pass filter and a 16bit analog-to-digital converter.
It can be combined with a KiBAT battery system to guarantee data protection.
Kistler has developed the KiBAT K3885 intelligent onboard battery, which cuts in if the cabled power supply fails, buffering components via the CrashLink2 bus.
It produces 400W for a 10 minute period with five colored LEDs indicating the status and if the energy level is low, an acoustic signal is emitted.
