Impact safety!

Magnetostrictive displacement transducers prove popular for impact testing
          
Impact testing of safety products such as crash helmets, calls for accurate measurement of displacement which is achieved by using transducers such as LVDTs and magnetostrictive devices.

An impact test determines the energy absorbed in fracturing a test piece at high velocity and this usually involves a large range of displacement. Sometimes LVDT's are used, but more usually MTS Temposonics transducers are recommended because of their much larger measurement range. MTS Temposonics are the original developers of the magnetostrictive technology and recognised world leaders for quality and service for this very rugged type of sensor. Based on the magnetostrictive principle displacement sensors are extremely accurate, highly reliable, offer absolute position measurement, can easily be installed and enjoy long trouble-free performance.
