66 -- C-MAN WATER/OCEAN TEMPERATURE PROBES SOL 51-QANW-0-00403 DUE 120899 POC Penny S. Parker, Contracting Officer, (228) 688-1705 and fax (228) 688-3153. E-MAIL: The contracting officer may be reached at the e-mail, Penny.Parker@ndbc.noaa.gov. The National Data Buoy Center (NDBC) desires the manufacture of 80 each Coastal Marine Automated Network (C-MAN) Water Temperature Probes in accordance with the NDBC specifications and drawings with options to purchase an additional 80 each prior to 12/31/2000 and 12/31/2001. Of the 80 units 50 units are to have 50 foot cables and 30 are to have 200 foot cables. The temperature probe shall be constructed to operate normally within the specified tempreature limits of -50 degrees C to +50 degrees C while completely submerged in fresh water, salt water, or a non-destructive antifreeze solution, for periods of up to 3 years. Probes will normally not be exposed to direct wave action, and are usually not installed in depths below 199 feet. The electronic data acquisition systems at the C-MAN sites vary in size and complexity, but each of them have the same -50 degrees C to +50 degrees C temperature sensor signal interface embedded in the elctronics circuit design. The interface is specifically designed around the Yellow Springs Instrument (YSI) Company 44XXX Series "Thermilinear Component, and a YSI 44312 precision resistor set. For the NDBC C-MAN water temperature probes, the 44020 thermistor and the 44312 resistor set (less resistor R1) are custom molded into a sealed, waterproof, stainless steel probe assembly. Resistor R1 is installed in the electronics interface as part of the bridge circuit for tempreature measurement. Fabrication of the probe assembly is not extremely complicated and should be well within the capability of many companies that maintain a high quality, professional, electro-mechanical production facility. The mechanical components are available from the YSI distributors. NDBC reserves the right to require inspection of the fabrication process by a designated technical or quality representative. Each temperature probe delivered must be vendor testedat 10 degree (+/-2 degrees C) intervals over the entire temperature range and be accompied by the vendor's certificate or data sheet showing the probe output is within +/- 0.5 degrees C of the reference termperature at each test point. New probes must complete a physical inspection and temperature chamber acceptance test at the NDBC facility within 30 days after delivery, prior to formal Government acceptance. All temperature probes delivered shall be warranted by the vendor to be free from all manufacturing defects affecting normal operation for 1 year. Site inspection required prior to award. Delivery FOB Destination 120 days after award. This is a small business set-aside. Requests for the IFB packaged should be faxed to Penny S. Parker at (228) 688-3153 or e-mailed to Penny.Parker@ndbc.noaa.gov. Posted 10/21/99 (W-SN393863). (0294)
