2 Presented by EHA team Context 1.Why not choose LVDT 3.Linear scale & LVDT - introduce the linear scale 4.Which way to assembe the parts -some example 5.History log 7.Reference 9.Q & A

3 Presented by EHA team why not choose LVDT LVDT Linear Scale LVDTLinear Scale InstallDifficultEasy PlaceinsideOutside

4 Presented by EHA team LVDT

5 Presented by EHA team Linear Scale

6 Presented by EHA team Which way to assembe the parts(1) - plunge pump & motor in cylinder for minimizing

7 Presented by EHA team Which way to assembe the parts(2) - Connecting motor and pump nearby - Linear scale in cylinder

8 Presented by EHA team The Best way we choose the specific reasons of why we select this way, Our team will make a detailed explanation next week
