The 3-component force sensor type 9397C from Kistler offers a maximum measuring range of 450 kN in the Z-axis and 100 kN in the X- and Y-axes. This makes it suitable, for example, for handling large measuring tasks such as recording impact forces in crash tests. Piezoelectric 3-component force sensors are used in industry to measure dynamic and quasi-static tensile and compressive forces. Thanks to a high natural frequency resulting from their high rigidity, these sensors enable the measurement of the smallest dynamic changes of very large forces in all three directions. The sensors are supplied calibrated and preloaded and can be used immediately after correct installation. A typical area of application is measuring the impact of aircraft landing gear on the runway. The forces acting on the aircraft landing gear during landing are simulated as part of the so-called 'landing gear drop test'. To do this, the entire landing gear is raised in a drop tower, the wheel is accelerated and then dropped onto the sensors. In order to measure the forces of 900 kN Fz and 400 kN Fx/y simultaneously, four sensors are installed in a dynamometer. Another application is the crash wall for high-speed trains, which has been in use in China since the end of July 2017. It has a measuring range that is 20 times higher than that of standard crash tests in the automotive industry.
