Description
Announcement Type: Special NoticeClassification Code: 6695
Announcement Number: NB685000-25-02257
Subject: Notice of Intent to Noncompetitively Acquire Thermometry Bridge System
The National Institute of Standards and Technology (NIST) Dimensional Metrology Group (DMG) delivers world class dimensional calibration services to support United States manufacturing and other industries. Precise temperature measurement is necessary to correct changes in the wavelength of light in air in our interferometer systems, as well as correct for changes in thermal expansion of gages under test. The NIST DMG is seeking a new thermometry bridge system to both replace ageing equipment and transfer the temperature scale from NIST calibrated thermometers to the secondary thermometers used across our various measurement services.
The NIST DMG is seeking one thermometry bridge system that includes one resistance thermometry bridge and one separate expansion unit with additional measurement channels. The system will be integrated into a length interferometer and serve double duty as a standard against which to calibrate secondary thermometers inside a temperature bath. Separating the main thermometry bridge unit and the expansion unit allows the bridge to be removed and sent for calibration without disrupting all the probe connections in the interferometer system.
This notice is not a request for a quotation. A solicitation document will not be issued and quotations will not be requested.
This acquisition is being conducted under the authority of FAR 13.106-1(b) via FAR 13.106-1(b). The North American Industry Classification System (NAICS) code for this acquisition is 334516, Analytical Laboratory Instrument Manufacturing.
The NIST DMG requires a precision thermometry bridge for our dimensional measurement services in order to meet the research and calibration needs of our group. Specifically, we require a thermometry bridge that: 1) provides pr...
