Bill of Materials

Procurement Description: TE Connectivity Optimus System

NASA Glenn Research Center (GRC) has a requirement to purchase Measurement Specialties TE Connectivity Optimus System for use at the 10x10 Supersonic Wind Tunnel (SWT). The 10x10 SWT at NASA GRC is standardized to using TE Connectivity/ Measurement Specialties products for pressure measurement. The system currently in use is the predecessor of the Optimus Pressure Measurement System and uses the same interface to connect with the NASA data system. The interface between the Optimus system and NASA s data system has been developed over the last decade and is well understood, being in use at various other facilities at NASA GRC.
