High Altitude Shipping Simulator
HASS
The HASS uses a Unitronics 570 PLC color touch screen.
The chamber will hold packaged product and simulate atmospheric pressure conditions while traveling to/through different altitudes. The chamber is controlled by a proportional regulator that feeds a venture type vacuum generator and monitored by a vacuum transducer. The proportional regulator is controlled by a feedback loop. The programming in the controller will allow the operator to define altitudes, ramp times and hold times. Operator can define a test of up to 5 steps example below:
RAMP TIME TARGET ALTITUDE HOLD TIME
00:04:00 10000 feet 00:30:00
00:02:50 5000 feet 00:45:00
01:00:00 10000 feet 01:00:00
00:05:00 8000 feet
00:03:00 0 feet
The program will provide a graphical representation of the altitude vs. time, as well as elapsed time and remaining time during a test.
