Title: Thermometry Bridge System
Background
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.
Minimum Requirements
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.
The system shall meet or exceed the minimum requirements identified below. All items must be new. Used or remanufactured equipment will not be considered for award. Experimental, prototype, or custom items will not be considered. The use of “gray market” components not authorized for sale in the U.S. by the Contractor is not acceptable. All line items shall be shipped in the original manufacturer-s packaging and include all original documentation and software, when applicable.
The Contractor shall provide the following one thermometry bridge system that meets the following minimum specifications:
Quantity: 1
Physical Specifications Two components: a main Is...
