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 .

• 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 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 also supports acquisition of data from a NMEA device connected directly to computer (instead of deck unit).

• 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)

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 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)

Note: 19plus V2 can only sample at 2 Hz (instead of 4 Hz) when equipped with Digiquartz pressure sensor. Additionally, 19plus V2 with Digiquartz pressure sensor is approximately 19 cm longer than strain gauge version, and requires a different cage (see PN 801270 under Spares & Accessories below).

Wet-pluggable connectors may be mated in wet conditions. Their pins do not need to be dried before mating. By design, water on connector pins is forced out as connector is mated. However, they must not be mated or un-mated while submerged. Wet-pluggable connectors have a non-conducting guide pin to assist pin alignment & require less force to mate, making them easier to mate reliably under dark or cold conditions, compared to XSG/AG connectors. Like XSG/AG connectors, wet-pluggables need proper lubrication & require care during use to avoid trapping water in sockets.

 
These selections include data I/O and pump Y-cable & data I/O cable compatible with data I/O - pump bulkhead connector.

SBE 5M pump is intended for providing pumped conductivity only, for improved conductivity response over non-pumped configuration. SBE 5M pump with plastic housing is supplied for 19plus V2 with 600 m housing; SBE 5M pump with titanium housing is supplied for 19plus V2 with 7000 or 10,500 m housing.

Larger, more powerful SBE 5P or 5T is required if also planning to pump auxiliary sensors (such as dissolved oxygen, etc.). Operational characteristics of SBE 5P & 5T are identical. SBE 5P plastic pump is supplied for 19plus V2 with 600 m housing; SBE 5T titanium pump is supplied for 19plus V2 with 7000 or 10,500 m housing.

SBE 5M or 5P/5T selection includes pump (with same connector type as 19plus V2), pump mount, & data I/O - pump Y-cable (cable compatible with connectors on 19plus V2 and pump). See cable DN 31551 for XSG/AG connectors, DN 32896 for wet-pluggable connectors.

General Information:

• 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 (XSG/AG 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 or 5T titanium pump instead of 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.

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 (XSG 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.

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.

These test cables are used for setting up system & uploading data from memory after recovery. Data I/O cable connects to 4-pin end of pump-data I/O Y-cable.

Connector type (RMG or wet-pluggable) must match 19plus V2 connector type. Applicable cable is included with 19plus V2; these are spares.

These Y-cables connect 6-pin data I/O - pump bulkhead connector to pump (2-pin leg) & to data I/O cable (4-pin leg).

Connector type (XSG/AG or wet-pluggable) must match 19plus V2 connector type. Applicable cable is included with 19plus V2; these are spares.

These cables are for hand-hauling 19plus V2 & acquiring real-time data. Cables are not intended for static working loads above 45 kg (100 lbs); working loads above 18 kg (40 lbs) may be difficult to handle without winch. Minimum recommended cable bend radius is 10 cm (4 in.) (e.g., 20 cm sheave block nominal diameter). See Application Note 59: A Load-Bearing Underwater Cable for Hand-Hauled, Real-Time Profiling.

Select a cable with connector (XSG or wet-pluggable MCBH) to match your 19plus V2.
