66 -- Setra Model 270 NDBC-5 Special Barometers

The National Data Buoy Center (NDBC) plans to negotiate exclusively with Setra Systems, Inc. for the purchase of 40 units of the Model 270 NDBC-5 Special Barometers, which operate within an 800 to 1100 mbar pressure range and provide a 0 to 5 VDC analog output. These barometers are specifically designed to be compatible with the automated weather buoys and coastal weather stations equipped with VEEP, MARS, or ARES electronic data acquisition systems used by NDBC. The equipment specification includes high accuracy, repeatability, and non-linearity standards, with a full range accuracy of ±0.05% full scale and repeatability of 0.01% full scale, ensuring reliable and precise environmental data collection. The barometers feature a robust mechanical design with specified mounting dimensions and a military specification electrical connector. They incorporate 9.22 turn potentiometers for zero and span adjustment and are temperature compensated for operation in the range of -20 to 50 degrees Celsius, with detailed calibration and temperature compensation data supplied with each unit. The contract, managed by the Department of Commerce’s NOAA office based in Kansas City, Missouri, is identified by solicitation number NWWG9502-6-27788, with Kurt L. Weilbaecher as the point of contact. This procurement aligns with the NAICS code 334419, indicating it falls under the manufacturing of measuring and controlling devices.
