Narrative:

Right after rotation heard circuit breakers popping and lost my airspeed and altimeter on the first officer's pfd. After checking in with departure we told them that we needed to return due to a problem with the aircraft. We were told to level at 3;000 and left turn to 270 degrees to setup for the left downwind; which is the longest runway available. After running the appropriate checklists for the level one items we declared an emergency and were vectored for a 30 mile final and setup early to make sure that none of the failures would effect our approach and landing. The landing normal and uneventful; after taxing in we found out that 7 circuit breakers had popped on rotation; causing the failures and error messages that we had received.
