SBE 45 MicroTSG Thermosalinograph
The externally powered SBE 45, typically mounted near the ship’s seawater intake, accurately determines sea surface temperature and conductivity from underway vessels. Measured data and derived variables (salinity, sound velocity) are output in real-time in engineering units. As an option, the SBE 45 connects to an AC-powered interface box near a computer. The interface box provides power and an isolated data interface; it contains a NMEA 0183 port for appending navigation data, and a port for appending the output of an optional remote temperature sensor (SBE 38). The SBE 38, installed at the seawater intake (ideally near the bow), measures sea surface temperature with minimal thermal contamination from the hull.
