Crash Barrier Sensor Matrix
Crash Barrier Sensor Matrix
Measure Distributed loads on
Crash Surface
This force sensor matrix is designed to be mounted
to fixed barrier to detect impacts on objects in tests.
It consists of 128 load cells arranged in 8 columns by
16 rows and be able to measure distributed loads on
crash surface. The force detecting direction is vertical
to the barrier and 2 kinds of rated capacities per unit
are available, 300kN and 500kN.
