EcoCTD v2.2 release
This is an updated design of the EcoCTD. It includes support for
- A RBRConcerto3++|fast8 with a connectorized end-cap (acting as CTD and logger)
- A RBRcoda T.ODO|fast (tau ~ 1 s) or the JFE RINKO fast-response (tau ~ 1 s)
- A WetLABS ECOPuck
This new release includes:
- A re-designed upper tube, that accommodates for the different form factor of a connectorized end-cap on the RBRConcerto. This allows a patch cable to be run from the Concerto to the hole in the top end of the EcoCTD for easy access to data and faster download. Previous versions (v1.0 and v2.0) relied on Wi-Fi download (battery consuming), or opening up the housing.
- the option to fit either RBRcoda T.ODO or JFE RINKO oxygen sensors.
- re-designed brackets to account for the thicker diameter of the cables provided by RBR.
The design still consists in a two-part aluminium tube (TUBE.LOWER_v2.2.step and TUBE.UPPER_RBRODO_v2.2.step or TUBE.UPPER_RINKO_v2.2.step) that encloses the three instruments listed above. The tube is designed to attach to an UnderwayCTD mechanical coupling at the top (TOP_END_v2.2.step) to be tethered to a ship-based winch.
Each instruments had corresponding clamps to secure them within the aluminium tube
- The RBRConcerto3++ is secured within the lower tube using two clamps: see RBR_CLAMP_v2.2.step
- The RBRcoda T.ODO|fast is attached using the clamp in ODO_CLAMP_RBR_v2.2.step
- The JFE RINKO is attached using the clamp in ODO_CLAMP_RINKO_v2.2.step
- The ECOPuck is secured using a two-part clamp (ECOPUCK_CLAMP_BOTTOM_v2.2.step and ECOPUCK_CLAMP_TOP_v2.2.step)
The two tubes are attached using the union clamp in UNION_v2.2.step.
Finally, two weight collars are attached onto the tubes to weigh the EcoCTD down (see WEIGHT_COLLAR_v2.2.step)
