SUMMARY

• Surface power and real-time data acquisition and control for water samplers and CTDs; two-way communication over single- or multi-conductor sea cable
• NMEA and Surface PAR interfaces
• Five-year limited warranty

DESCRIPTION

The rack-mountable SBE 33 provides power and real-time data acquisition and control for an SBE 32 Carousel Water Sampler that has the SBE 33 interface option installed in its pylon. The SBE 33 is compatible with all Carousel sizes -- full size, compact, and sub-compact. When powered and controlled by the SBE 33, the Carousel can be used:

• with an SBE 19, 19plus, 19plus V2, 25, 25plus, or 49 CTD
• without a CTD
• with a Neil Brown Mk III CTD (requires optional interface for both SBE 32 and 33)

The SBE 33 can also provide power and real-time data acquisition and control for the smaller SBE 55 ECO Water Sampler used with an SBE 19, 19plus, 19plus V2, 25, 25plus, or 49 CTD, or no CTD.

The SBE 33 / Water Sampler system provides real-time data telemetry and surface power for the CTD, and permits Water Sampler control with the SBE 33 front panel buttons or via our Seasave software. Bottles are sequentially or in any order; the front-panel LED display indicates which bottles have been fired. Other features include:

• NMEA Interface for navigational data -- SBE 33 decodes messages output from navigation devices supporting NMEA 0183 protocol.
• A/D converter for Surface PAR sensor -- SBE 33 supplies 12 volts to power the sensor.

Decoded latitude and longitude, and Surface PAR data, are appended to the CTD data stream in the SBE 33, and passed to the computer for storage and/or display with the CTD data.

The SBE 33 can also be used with the PDIM when a water sampler is not available or needed. The PDIM provides the same power and CTD data interface functionality as the water sampler, but without water sampling capability.

The SBE 33 is supplied with a powerful Windows software package, Seasoft^© V2, which includes:

• Seaterm^© and SeatermV2 -- terminal programs for easy communication and data retrieval.
• Seasave^© -- program for real-time data acquisition and water sampler bottle firing control.
• SBE Data Processing^© -- modules for calculation, display, and plotting of temperature, conductivity, pressure, auxiliary sensor data, and derived variables such as salinity and sound velocity.
