RBRlegato⁴ C.T.D
Pump-free CTD for gliders and AUVs rated to 1250dbar, with multi-rate sampling up to 16Hz and 90% lower power than pumped CTDs.
Description
The RBRlegato⁴ C.T.D is optimised for gliders and AUVs and derives salinity, density and sound velocity. Its rugged inductive conductivity cell is unaffected by surface contaminants or freezing conditions.
Key features
- CFD-optimised, low aspect ratio, self-flushing cell that needs no pump
- Power draw of 46mW at 2Hz or faster and 18mJ/sample at 1Hz or slower; RBR states 90% lower than traditional pumped CTDs
- Multi-rate sampling up to 16Hz; 1250dbar depth rating
- Wet-bay and integrated configurations
- Controls additional sensors such as the RBRcoda³ T.ODO, RBRtridente and RBRquadrante
Applications
Oceanographic payloads for underwater gliders and AUVs.

System / Package
WEKA Guard & WEKA Protector Type T – Boxcooler Protection System
Protection units exclusive to WEKA copper-nickel boxcoolers: the Guard shields the cooler from welding currents during construction; the Protector Type T guards against ICCP and stray currents in service and keeps the natural anti-fouling layer active — no ICAF needed.
