High Altitude Low Pressure Simulation Test Chamber/Altitude Test Chamber
Pressure is the main test variable in the LEATCH high altitude low pressure simulation chamber. Chamber pressure runs from atmospheric down to -98 kPa, 133 Pa or 0.05 Torr, which covers altitudes up to 100,000 feet, while temperature is held at the test value. The chamber is a custom system for simultaneous temperature and altitude testing. Two common uses are testing avionics and other aerospace equipment under service conditions, and simulating the high-altitude environment of mountainous regions. Standard sizes are LEATCH-150, LEATCH-225, LEATCH-408, LEATCH-800 and LEATCH-1000.
Pressure and altitude control
A vacuum pump sized for the climb and dive rate of the application evacuates the working room. Altitude control is automatic and integrated with the temperature controller, so the operator does not set altitude level by hand. Pressure control tolerance is ±0.1 kPa at or below 2 kPa, ±5% from 2 to 40 kPa and ±2 kPa at or above 40 kPa. Depressurization takes 20 to 50 minutes, depending on chamber size.
Temperature system
A SUS 304 stainless steel high-speed heater, compressor refrigeration with finned evaporator and a cooling fan for air circulation set chamber temperature. Lower limits run from -160 °C to 0 °C and upper limits from +150 °C to +500 °C. Fluctuation is ±0.5 °C and accuracy ±2.0 °C at room pressure. Heating from +20 °C to +150 °C takes 60 min or less, cooling 45 to 90 min. Humidity control is optional when the altitude system is off. The inner chamber is SUS 304 plate with PU and fiberglass wool insulation.
