Abstract
This report describes the design, building and testing of a high precision data acquisition system that is able to function in high pressure environments. The system uses an FPGA as its controller sending and receiving information to and from a data conversion device with the AD4630 as its ADC and the DAC8811 as its DAC. The system is tested in a pressure chamber which was pressurised up to 500 bars of pressure and the performance difference was found to be negligible. The system had to be proven to be scalable to 16 channels and these 16 channels had to fit inside a volume of 100ππ3.
