TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
A directly immersible cryogenic MEMS pressure sensor will be developed. Each silicon die will contain a vacuum-reference and a tent-like membrane. Offsetting thermal effects allow the device to operate over a wide temperature range. Using a patented, proven design the device is capable of continuous low-power operation and provides accuracies as low as 0.002 % of reading.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
NASA applications include:
Tank leak detectors inside the vacuum/MLI space.
Transfer line pressure sensors with no trapped volume, eliminating problems with vent/purge operations.
PVT-based mass gauging systems requiring high accuracy.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Non-NASA commercial applications include process industries such as foods, chemical, and semiconductors; superconductor research; high-volume gas delivery systems such as LN2; and biological research applications such as cryopreservation and cryobiology.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
