pressure sensor stuff
- i totally forgot that at this size (~10cm diameter of tank) capillary action is actually very strong; LN2 creep upwards into the penetration for sensing
- since the pressure sensor isn't relevant for the relief valve, we should really reconsider the non-invasive options just because of this
- foil strain gauges prob best solution?
