Altitude Test Chamber
The LEATC altitude test chamber combines a temperature test chamber with a vacuum system that simulates altitude from ground level to 100,000 feet. Aerospace and electronics test laboratories use it to expose avionics, components and packaging to the low pressure they meet in flight, and to reproduce the thin air of mountainous regions. Five standard sizes run from LEATC-150 to LEATC-1000; interior size can also be specified by the customer.
Design
The specimen sits in a SUS 304 stainless steel inner chamber with PU and fiberglass wool insulation inside a powder-coated stainless steel exterior. A vacuum pump, sized for the climb and dive rate of the application, lowers chamber pressure. Altitude control is automatic and integrated with the temperature controller, with no manual setting of altitude level. Pressure control tolerance is ±0.1 kPa up to 2 kPa, ±5% from 2 to 40 kPa and ±2 kPa above 40 kPa, with 0.1 kPa resolution (1 Pa or 0.0001 kPa optional).
A SUS 304 high-speed heater and compressor refrigeration with ADP dew point dehumidifying cover lower limits from -160 °C to 0 °C and upper limits from +150 °C to +500 °C. Temperature 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 without load. Humidity control, 20 to 98% RH, works when the altitude system is off.
