Q&A

How are water quality sondes mounted to moorings?
down-arrow
When measuring near the surface, water quality sondes can be housed inside a slotted deployment pipe that is threaded directly to the bottom instrument well on the buoy hull. This allows instrument access for periodic cleaning and calibration without having to pull the buoy out of the water. If the project requires measurements at depth or at multiple depths, NexSens offers instrument clamps and mooring cages for mooring lines, as well as bottom platforms when sondes need to be bottom referenced instead of surface referenced.
How do I connect sensor cables to the data buoy?
down-arrow
For customer integrations, cables can be run through one of six ports on the passthrough data well lid and secured with a supplied cable gland. The backside of the cable gland should be filled with epoxy or sealant to prevent water ingress. Alternatively, NexSens can supply a waterproof bulkhead connector with mating pigtail for splicing with user-supplied sensor cables. This allows for a quick disconnect of the cable at the lid. When using an X2-CB or X2-CBMC data logger on a NexSens integrated system, all supplied sensor cables are terminated with mating UW plug connectors or MCIL-8-FS connectors.
How do I mount a Doppler current profiler to the data buoy?
down-arrow
The mounting for an acoustic Doppler current profiler (ADCP) is instrument-dependent. NexSens offers several ADCP mounts for Nortek instruments, including the Aquadopp and Signature Series ADCPs. The mounts must be designed in such a way that the acoustic beams are unobstructed by the buoy and mooring. Custom mounts are also available based on project-specific needs.
