  Since mid-2007, the existing storage ring PETRA at DESY is reconstructed towards a dedicated third generation hard x-ray light source operating at 6 GeV with 100 mA stored current. The reconstruction includes the total rebuilding of one-eights of the storage ring. In this part the FODO lattice of the arcs is replaced by double-bend achromat cells, resulting in straight sections for 14 insertion device beamlines. Damping wigglers with a total length of 80 m are installed to reduce the emittance down to the design value of 1 nm rad. In order to fully benefit from this low emittance, beam stability is a crucial issue. For the achievement of the required performance and to allow a safe machine operation a number of beam instrumentation is required. Here the diagnostics system for the electron beam is presented with special emphasis on the essential instruments, i.e. the high resolution BPM system, profile monitors, feedback systems, and the machine protection system.
