Piezoelectric force measuring elements, SmartCrash system, with digital data output / 9350B
9350B
The piezoelectric SmartCrash force measuring element with integrated electronics is able to measure three orthogonal components Fx, Fy and Fz of dynamic forces in any direction. It is predestinated for measuring high dynamic impact forces e.g. during crash test procedures for automotive R&D.
Características/ventajas principales
- Wide measuring range (Fx: 500 kN; Fy, Fz: 100 kN)
- High sensitivity
- Excellent linearity over total measuring range
- Integrated data preprocessing and data storage
- Digital data output
- TEDS functionality (calibration data and sensor identification)
- Preloaded and calibrated
The SmartCrash force measuring element consists of a top and base plate, the piezoelectric quartz sensor preloaded by a hollow expansion screw between base plate and top plate and an integrated electronics for data pre-processing. Each individual SmartCrash force measuring element measures the three orthogonal forces Fx, Fy and Fz of the forces affecting during the crash. The piezoelectric sensor in the force measuring element generates a proportional charge on the force, which is amplified and processed. A unit for digitization of the analog signals (DiMod module) is incorporated in each individual SmartCrash force measuring element. The charge signals are converted into a voltage signal, digitized by an A/D converter and stored in a central data recorder which simultanously executes the parametrization and control.
