Barrier Load Cell

Summary

Measures distributed forces on crash surface.

This load cell is designed to be mounted to fixed barrier to detect impact on objects in tests.
It consists of 128 load cells arranged in 8 columns by 16 rows and be able to measure distributed forces on crash surface.
The force detecting direction is vertical to the barrier and 2 kinds of rated capacities per unit are available, 300 kN and 500 kN.
