This line plugs into our data acquisition board (DAQ) and allows us to get a reading from the load cell.
We didn't have quite enough wood to make it all the way around with the support bars...

Load Cell Stand for a K-size Nitrous Oxide Tank
For the Boston University Rocket Propulsion Group's MKIII hybrid rocket motor, we needed to find a way to measure how much nitrous oxide we had put into the rocket. To solve this problem, I used a load cell rated to 500 lbs and built a stand to hold the cell and the tank. The stand is built out of pine and I added 1/8" aluminum sheets where the load cell bolts go through the plywood for added support and to dissipate the force over a larger area.
