SBE 19plus V2 SeaCAT Profiler
Configuration Details

19plus V2 in plastic housing with SBE 5M plastic pump & associated plumbing (plumbing configuration shown for 19plus V2 to be deployed in vertical orientation)

19plus V2 is intended primarily as a profiling CTD, sampling at 4 Hz, but can also be used in moored mode to obtain long-term time series data. 19plus V2 is powered by internal batteries, & records data in memory.

In addition, in profiling mode, 19plus V2 can be deployed:

• With SBE 36 CTD Deck Unit & Power Data Interface Module (PDIM), which provide power & real-time data handling capability over single-conductor sea cables. For PDIM, specify 19p-9a or -9b; order SBE 36 separately.

• With SBE 32 Carousel Water Sampler & SBE 33 Deck Unit, which provide power, real-time data handling capability, & real-time water sampler control over single-conductor sea cables. Order SBE 32 (32, 32C, or 32SC) & SBE 33 separately.

• With SBE 32 Carousel Water Sampler & Auto Fire Module (AFM), which provide autonomous water sampling capability. Order SBE 32 (32, 32C, or 32SC) & AFM (by selecting appropriate Carousel operating mode configuration in 32, 32C, or 32SC listing) separately.

• With SBE 55 ECO Water Sampler & SBE 33 Deck Unit, which provide power, real-time data handling capability, & real-time water sampler control over single-conductor sea cables. Order SBE 55 & SBE 33 separately.

• With SBE 55 ECO Water Sampler, which has built-in capabilities similar to that of an SBE 32 integrated with an AFM, providing autonomous water sampling capability. Order SBE 55 separately.

Notes:
- Optional auxiliary sensors on CTDs not shown.
- (real-time systems) Computer, slip-ring-equipped winch, conductive cable, & NMEA 0183 navigation device not supplied by Sea-Bird.
- (real-time systems) Seasave version 7.18 or later also supports acquisition of data from a NMEA device connected directly to computer (instead of deck unit).

See SBE 16plus V2 for similar CTD intended for moored applications instead of profiling applications.

Pressure sensor is installed in connector end cap, & is not field replaceable / swappable. While highest pressure rating gives you most flexibility in using 19plus V2, it is at expense of accuracy & resolution. It is advantageous to use lowest range pressure sensor compatible with your intended maximum operating depth, because accuracy & resolution are proportional to pressure sensor's full scale range. For example, comparing 2000 & 7000 m sensors --

• 2000 m sensor:
  initial accuracy = 2 m (= 0.1% * 2000 m),
  resolution = 0.04 m (= 0.002% * 2000 m)
• 7000 m sensor:
  initial accuracy = 7 m (= 0.1% * 7000 m),
  resolution = 0.14 m (= 0.002% * 7000 m)

Digiquartz pressure sensors provide better accuracy (0.02% of full scale range vs 0.1% of full scale range) & resolution than strain gauge pressure sensors. See SBE 19plus V2 Strain Gauge Pressure Sensor Options above for photo of pressure sensor port; when used with Digiquartz, nylon pressure capillary fitting screws into port.

While highest pressure rating gives you most flexibility in using 19plus V2, it is at expense of accuracy & resolution. It is advantageous to use lowest range pressure sensor compatible with your intended maximum operating depth, because accuracy & resolution are proportional to pressure sensor's full scale range. For example, comparing 2000 psia (1400 m) & 6000 psia (4200 m) sensors --

• 2000 psia (1400 m) sensor:
  initial accuracy = 0.28 m (= 0.02% * 1400 m)
• 6000 psia (4200 m) sensor:
  initial accuracy = 0.84 m (= 0.02% * 4200 m)

Standard SBE 5M pump is intended for providing pumped conductivity only, for improved conductivity response over a non-pumped system. Larger, more powerful SBE 5P or 5T is required if also planning to pump auxiliary sensors (such as dissolved oxygen, etc.).

SBE 5P plastic pump is rated for 600 m; SBE 5T titanium pump is rated to 10,500 m. Operational characteristics of SBE 5P & 5T are identical.

• 19p-6, -7, & -8 include auxiliary sensor, mount, & straight cable to connect sensor to 19plus V2 bulkhead connector. See auxiliary sensor specification sheets (SBE 43, 18, 27) for sensor descriptions. Auxiliary sensor connector type (standard or wet-pluggable) must match 19plus V2 connector type.
• If connecting 2 sensors to 1 bulkhead connector, YMOLD (to create a y-cable) applies in addition to 19p-6, -7, & -8 price.
• Additional sensors not listed here -- fluorometers, transmissometers, turbidity meters, PAR sensors, etc. from third party manufacturers -- are compatible with 19plus V2. These sensors can be purchased from Sea-Bird & integrated with 19plus V2 at our factory, or you can purchase mount kits & cables from Sea-Bird & perform integration yourself. See Third Party portion of price list.
• User can change sensors on 19plus V2 in field. However, as noted above, Y-cable is required to connect 2 auxiliary sensors to 1 bulkhead connector on 19plus V2; each Y-cable is unique to sensors being integrated, so changing sensors may require changing Y-cable. In addition, sensor mechanical mountings may need to be changed to suit selected combination of sensors.

Sensor-Specific Information:

• SBE 43 -- SBE 43 is available in 7000 m titanium (19p-6a or -6b) or 600 m plastic (19p-6c or -6d) housing. SBE 43 is plumbed between conductivity sensor & pump. Consequently, system requires more powerful SBE 5P plastic (19p-4a) or 5T titanium pump (19p-4b) instead of standard 5M pump; operational characteristics of SBE 5P & 5T are identical.
• SBE 18 & SBE 27 -- Note that these sensors are only available with a depth rating to 1200 m.

Moored Application Information:

• SBE 43 -- If intending to use 19plus V2 in moored application, contact Sea-Bird to specify integration with an SBE 43 in Moored Configuration instead of Profiling Configuration (1 mil membrane vs 0.5 mil membrane for enhanced long-term stability; & black Tygon tubing vs clear Tygon tubing for plumbing, for reduced bio-fouling). Alternatively, we recommend use of the SBE 63 Optical Dissolved Oxygen Sensor for moored applications.
• SBE 18 & SBE 27 -- Sensors are not recommended for use in moored applications. See Application Note 76: pH or pH/ORP Sensors and Moored Applications.

SBE 36 CTD Deck Unit & PDIM provide surface power & real-time data acquisition & control for 19plus V2, allowing deployment with 10,000 m long single-conductor sea cables. SBE 36 is installed on ship, while PDIM is mounted on or near 19plus V2. See SBE 36 description for more information on interface.

SBE 33 Deck Unit is typically used to provide surface power & real-time data acquisition & control for 19plus V2 & SBE 32 (32, 32C, or 32SC) Carousel Water Sampler or SBE 55 ECO Water Sampler. However, it can be used with PDIM instead of Carousel or ECO to provide same functionality as SBE 36 & PDIM.

PDIM housing is anodized aluminum, & is rated to 6800 m. PDIM connector type (standard or wet-pluggable) must match 19plus V2 connector type.

19p-9a & -9b do not include SBE 36 or 33 Deck Unit; order separately.

 
Can substitute SBE 33 Carousel Deck Unit for SBE 36 CTD Deck Unit.

Note: 19plus V2 with optional Digiquartz pressure sensor requires a longer cage (PN 801270) than 19plus V2 with standard strain-gauge pressure sensor. PN 801270 cage does not fit in this Hardigg shipping case; contact Sea-Bird to discuss purchasing a larger case.

Price for 19p-10 reflects a credit for deletion of our standard wood crate.

Notes regarding features of Hardigg case supplied by Sea-Bird:
1. Case does not have wheels, because we prefer that the case is not rolled along the ground:
- Rolling along the ground could cause unnecessary vibration of the CTD.
- Rolling over a curb could cause unnecessary impact to the CTD.
2. Case has small holes on each metal latch, into which you could insert a small, TSA-approved lock or some zip ties. Case cannot accommodate a large padlock.

Many users purchase optional cage to protect system from damage during deployment.
