📥 Download Our Latest Technical Note : “Low outgassing accelerometers and cables for thermal vacuum and vibration test environments”
Outgassing is a critical issue when performing vibration tests in thermal vacuum chambers. Any gas released from accelerometers or cables can compromise sensitive spacecraft components, particularly optical instruments. That’s why PCB Piezotronics offers a full range of low outgassing sensors and cable assemblies, specifically qualified for space-grade test environments.
These products are designed with hermetic housings, certified materials, and validated through NASA and ASTM standards for Total Mass Loss (TML ≤ 1%) and Collected Volatile Condensable Materials (CVCM ≤ 0.1%).
What’s Inside:
- Why standard accelerometers and cables can contaminate vacuum chambers
- How shear-mode sensor design and laser welding improve hermeticity
- Which materials to avoid — and which are certified low-outgassing
- Leak testing methods (bubble test, helium mass spectrometry)
- Real-world case study: NASA Suomi NPP Satellite testing
