Manual revision 016 Section 2: Description of FastCAT SBE 49
9
A FastCAT is supplied with:
• Plastic housing for depths to 350 meters (1150 feet) or
titanium housing for depths to 7000 meters (22,900 feet)
• Strain-gauge pressure sensor
• Integrated T-C Duct
• Internal pump for flow-controlled conductivity and temperature response
• XSG or wet-pluggable MCBH 4-pin I/O bulkhead connector
• Straight pump exhaust fitting, providing high quality data for
most applications
• Pump exhaust tee fitting, for slow profiling applications – tee fitting is
included in spares kit that ships with FastCAT, and can be easily
substituted for the straight pump exhaust fitting in the field. See
Optimizing Data Quality in Section 4: Deploying and Operating
FastCAT for guidelines on use of the straight fitting vs. the tee fitting.
• Optional anti-foulant device fitting and expendable Anti-Foulant Devices
for long deployments
The FastCAT can be used with the following Sea-Bird equipment:
• SBE 32 Carousel Water Sampler and SBE 33 Carousel Deck Unit OR
SBE 55 ECO Water Sampler and SBE 33 Carousel Deck Unit -
The SBE 32 or SBE 55 provides +15 VDC power to the FastCAT. The
CTD data from the FastCAT is converted into single-wire telemetry for
transmission over long (10,000 meter [32,800 feet] sea cables. Bottles
may be closed at any depth without interrupting CTD data via software
control using the Seasave program or from the front panel of the
SBE 33 Deck Unit. See the SBE 33 manual for system operating details.
Note:
The FastCAT’s pump is not designed to
be used to pump water through other
sensors. Other sensors requiring
pumped water need a separate pump.
Notes:
• The SBE 32 Carousel is a 12-, 24-, or
36-bottle water sampler, available
with bottle sizes up to 30 liters. The
SBE 55 ECO is a 3- or 6-bottle water
sampler with 4-liter bottles.
• Seasave also supports acquisition of
data from a NMEA device connected
directly to the computer (instead of
the deck unit).
• SBE 33’s NMEA interface was
optional prior to 2010, and the
Surface PAR interface was optional
prior to 2012.
