To accelerate this project's development, it is time to start tackling other construction problems. The first major issue is to get the Data Acquisition System figured out. This has been a headache for a long while as the DAQ board being used, a LabJack U3, doesn't seem to want to read the values from the pressure transducer. The thermocouples are a whole other problem that still needs a solution as well. To find whether or not the board was cooperating with the hardware being used, the load cell was set up on the bench and hooked up to a 12V power supply. I had not realized until measuring the voltages that the load cell outputs a very small voltage that would need to amplified and scaled to properly measure the amount of force the load cell is under. Applying a small amount of clamping force in the vise on the load cell showed that it outputted voltages in the mV not V. The values being read were between 0.000V and 0.017V. The next logical step would be to purchase an amplifier or figure out a way to amplify the signal with already existing components in the shop.
Other issues faced today was realizing that the wrong contact tips for the aluminum spool gun on the MIG welder were purchased and the wire would not feed through them. The through holes were 0.8mm when they needed to be 0.9mm. Therefore, no practice welds or fuel tank welding was done.
