I am in the process of putting together a data acquisition system which will need to operate at 1/10 atmosphere. Apart from the obvious point of outgasing with electrolytic capacitors what else should i be concerned with. The system will consist of a FED basic controller, RS485 half duplex io port and MAX176 12 bit a/d plus associated signal conditioning for a very sensitive large area photodiode... Any helpful comments apreciated...
