In-Situ AquaTroll X-Series Integration Guide


The In-Situ Series of Multi-Parameter Water Quality Sondes are compatible with NexSens X-Series data loggers using SDI-12.

Sensor Setup

Before the sensor can be deployed, complete sensor setup by following the manufacturer’s guidelines.

Note: Be sure to note the parameter order in the software, as this must align with selected parameters in the logger.

 

Connecting with X-Series Loggers

Next, the sensor will need to be connected to the X-Series logger through CONNECT software. If you have not yet done so, set up the project in WQData LIVE.

  1. Connect the sensor using the supplied cable to one of the open sensor ports on the logger and note the port number.
  2. Plug the X3 into the USB port of the computer and power it on with the AC power cable.
  3. Open CONNECT and select the SENSOR tab.
    Open CONNECT and select the SENSOR tab.
  4. Click Add and select In-Situ from the Manufacturer drop-down. Then select the appropriate model.
  5. Adjust the SDI-12 address if needed and select the port number.
    1. If using multiple SDI-12 sensors, ensure each has a unique address.
  6. Select either Continuous or Switch in the Power drop-down.
    1. Switch is recommended for the sensor.

  1. Select Save Sensor Profile.
  2. Complete the setup for all other sensors, and then click Save.
  3. Name the Sensor Profile List and select Ok.
    Save Sensor Profile List.
  4. Complete system setup by clicking Deploy.

  1. Confirm that data is being transferred to WQData LIVE at the next interval (default is 10 minutes).

 

Buoy-Based Deployments

First, follow the appropriate User Guide in the Knowledge Base for buoy assembly. There are two options for near-surface measurements and a third option for water column measurements:

 

1. Cage Mount

Use the NexSens Small Instrument Cage Mount to attach the sensor to the buoy cage.

  1. Strap the sensor to the cage leg with the mount and cable ties (as shown). The mount is supplied with a rubber adhesive liner to prevent the sensor from sliding.

  2. Further secure the assembly by adding a few additional ties to the cable.

2. Buoy Deployment Pipe

Optional perforated deployment pipes can be fitted to most NexSens CB– and XB-series buoys. Deploying the sensor inside the pipe provides easy access for maintenance and recalibration.

3. Water Column

Use the NexSens Instrument Mooring Clamp to securely attach the sensor to a sensor mooring line at the desired depth in the water column.

Shore-Based Deployments

For dock, pier, or bank deployments, it’s best to secure the sensor in a perforated PVC pipe. Extend the pipe into the water and deploy the sensor.
