Recent Design Updates and Selection Considerations for High Temperature and Cryogenic Aerospace Sensors
. The same sensor might be required to withstand radiation and be used in monitoring vibration inside a nuclear power plant or on a space vehicle, or the cryogenic conditions of liquid propellants. These environments present a multitude of measurement challenges. Materials and construction must

Considerations for Step Motors in Space Applications
The environmental challenges of space-related applications are immense, and include vacuum (10-8 to 10-12 torr), deep space cryogenic (20 Kelvin), thermal shock (sun at +200°C to shade at -200°C in one to two seconds), launch vibration, ionized particles and radiation. In addition

Polyimide
temperature for interrmittent exposure can range from cryogenic to as high as 900 F. Glass-fiber reinforced versions retain over 70% of their flexural strength and modulus at 480 F. Creep is almost nonexistent, even at high temperatures and deformation at under load (4,000 psi) is less than 0.05% at room
