Scalable levels of testing
Due to the unique nature of projects, the level of testing and verification required for each project will change. To accommodate this, various degrees of testing and verification are available in the HR Series product line. This ranges from Level 3 sensors that undergo a limited subset of acceptance screening tests to Level 1 sensors which are fully screened and qualified for the highest confidence level possible. This allows sensors to be selected that are appropriately qualified for the application.
Other verification steps include:
- Thermal shock conditioning and stabilization bake to settle the sensor into a stable temperature curve
- Sensors are exposed to one week of continuous operation at elevated temperatures, then exposed to 100 thermal shocks between room temperature and liquid helium (4.2 K) to weed out early-life failures
- Sensor inspected for any visual defects at various stages of production
