Recorded Pressure Issue

I try to record absolute pressure versus flow time in a sliding mesh simulation.
i've created a vertex in the flow to plot the absolute pressure (with 'area weighted average' function)
But the pressure signal is apparently not very good, and i don't know why!
I check time steps, discretization, mesh...
Why is there some discontinuities in the pressure signal?
I've modelized a rotor with very small impellers (like 1 mm thick), with only 6 impellers (see the black picture here : http://www.cfd-online.com/Forums/members/benjikos-albums-image-picture195-2d-geometry.jpg )
Could anyone help me?
Thanks a lot!
