- Description
- Amendment 001 to NRMAD00404154SLW Salinity being a derivative of the temperature and conductivity of sea water, our coral reef monitoring requires a Conductivity precision factor greater than or equal to 0.0003 S/m accuracy with a 0.00001 S/m resolution. The Temperature must also have a 0.002 0C accuracy with a 0.0001 resolution. The instrument must be supplied with internal memory storage, internal integral pump, internal battery pack and must also have an external RS232 interface for communication to our data logger. The CTD sensor records the conductivity, temperature and depth internally while simultaneously up loading the data via the RS-232 interface to our data logger, which transmits the data hourly via GOES satellite. If any problems arise and transmission to the GOES satellite is stopped or the external power drops below 12vdc, no conductivity, temperature or depth data is lost.These sensors will be deployed two to a station at all CREWS (Coral Reef Early Warning System) monitoring deployments in both the Atlantic and Pacific networks. One just below the surface and one at depth to record and transmit their respective environments. Required Specifications Conductivity: Range 0 to 70 mS/cm, Accuracy 0.003 mS/cm, Resolution 0.0001 mS/cm Temperature: ?5 to +350C, Accuracy 0.002, Resolution 0.0001 Depth: 0 to 20 meter Full Scale, Accuracy 0.1% of Full Scale, Resolution 0.002% Full Scale Memory: 2048k Byte non-volatile FLASH memory Data Storage: Conductivity, Temperature, Depth and Time = to 185,000 samples Real-Time Clock: Accuracy ? 2.6 minutes/year Internal Battery backup: 80,000 samples (incase of solar power failure) 7.2ahr Lithium battery pack, which can be, shipped separate from instrument without hazardous material restrictions External Input Power: 40ma @ 9 to 24vdc Quantities Needed 7 Each Conductivity Temperature and Pressure Recorders with Serial interfaces, Memory and internal Pumps ? Includes Pressure housing, mooring clamp, 2 MB Flash memory, RS-232 interface, lithium battery (non-hazardous), Software and complete documentation. 7 Each 20 meter strain gauge pressure sensor 7 Each RS-232 serial interface with external power input capability (4-pin female connector) 7 Each Data/Power interface cables 16 meters in length. 7 Each Dummy plug, 4-pin male. Pricing should be submitted in accordance to the quantities needed. The closing date remain to be by COB, Jul 12 2004, CST. Offers can be faxed to 816-426-530 Attn: Sharon Walker
