High Altitude Shipping Simulator (HASS)

The HASS simulates shipping a packaged box of dry goods at high altitudes. This is an essential quality control machine that dictates the sustainability and survivability of any good. 

The number of peaks, the heights of the inclines (or peak), the ramp speed (or rate), and the time at the peak are configurable through the controller. The vacuum level of the chamber is controlled by modulating a proportional valve. The proportional valve's input is compressed plant air that is regulated down to approximately 60 psi. 

Acceptable input air regulator pressures are 55 to 80 psi. Lower pressures will not allow enough vacuum to build in order to simulate 12,000 feet of altitude. The proportional valves output is connected to the input of a Venturi vacuum generator different vacuum levels and ramp rates can be achieved.
