Manual revision 006 Section 2: Description of SBE 19plus V2 SBE 19plus V2

Configuration Options and Plumbing

The standard SBE 19plus V2 includes an externally mounted SBE 5M pump,

which provides a constant flow rate through the conductivity cell regardless of

descent rate. If configured with a dissolved oxygen sensor or pumped

fluorometer, the more powerful SBE 5T (titanium) or 5P (plastic) pump is used.

Any of these pumps is powered via a cable connected to the 2-pin leg of the Y-

cable (which is connected to the Data I/O, Pump, and External Power bulkhead

connector on the sensor end cap).

The 19plus V2 can be configured with a wide range of auxiliary sensors.

Three standard 6-pin bulkhead connectors on the sensor end cap serve as the

input ports for the auxiliary sensor signal voltages and provide power to the

sensors.

Additionally, a standard 4-pin bulkhead connector on the sensor end cap is

provided for interfacing with one of the following RS-232 sensors:

• SBE 38 secondary temperature sensor

• WET Labs sensor - single, dual, or triple channel ECO sensor; WETStar;

or C-Star

• Pro-Oceanus Gas Tension Devices (up to two GTDs can be integrated)

• Aanderaa Optode 4330 or 4835

A 19plus V2 is typically deployed in a vertical position. However, when used

with an SBE 32 (full size) Carousel Water Sampler, the 19plus V2 is deployed

in a horizontal position in an extension stand below the Carousel. Pump

placement and plumbing for a horizontal mount is different than that for a

vertical mount.

Sea-Bird provides the system with pump placement and plumbing for the

desired orientation at the time of purchase. However, you may reorient the

system later as needed. Failure to place the pump and plumbing properly can

trap air, preventing the pump from working properly.

Shown below are schematics of the system configuration for vertical and

horizontal deployment. In the schematics, cables are omitted for clarity.

Secure each tubing connection with 2 cable ties.

Vertical Mount

• Place the exhaust as far from the intake as possible, so that exhaust water

is not pulled into the intake. Failure to place the exhaust away from the

intake can lead to errors in temperature data, because the pump transfers

heat to the exhaust water.

Note:

See Section 4: Deploying and

Operating SBE 19plus V2 for

pump setup and operation.
