Pressure Transducers

NASA's Shared Services Center is procuring pressure transducers for use in a regenerative fuel cell application at NASA Glenn Research Center. The solicitation requires 44 pressure transducers in two configurations: 20 low-pressure units with 0-160 psi operational range and 24 high-pressure units with 0-3000 psi operational range. This is a brand name requirement specifically for Wika pressure transducers (part numbers #76247721 and #76247722) with detailed technical specifications including 4-20 mA signal output, compatibility with hydrogen, oxygen, and water, oxygen cleaning to ASTM G93 standards, and FM Class I, Div. 2, Group B approval. The procurement will be evaluated based on best value to the government, considering qualitative criteria such as minimizing installation time, reducing maintenance operations, and enabling future modifications. The solicitation was posted on July 24, 2025, with quotes due by July 29, 2025 at 1:00 p.m. CT.

This procurement is set aside for small businesses under the Total Small Business set-aside program, with quotes obtained from Ryan Herco Flow Solutions mentioned in the Q&A documentation. The technical specifications include commercial grade components with 0-30 VDC power supply, 0.15% span accuracy, 300 ms response time, and 4-pin MIL-DTL-26482 bayonet connectors. The transducers must operate at temperatures not exceeding 100°C with ambient temperatures not exceeding 40°C, and feature 1/4" female face seal fluidic ports for single port/interface configuration. Performance will take place at NASA Glenn Research Center in Cleveland, Ohio, with installation required in the system by mid-September 2025. Vendors must be registered in SAM.gov and comply with specific provisions regarding telecommunications equipment and export control regulations.
