ST850 Smart™ Sensor SST Thru-hull NMEA 2000®
Part NumberST850SS-2000
Speed and Temperature
The ST850 is a low-profile, retractable, thru-hull sensor that computes accurate speed and temperature data and sends it to any NMEA 2000® network. These low-profile units are nearly flush, minimizing drag with only 5 mm (3/16") extending outside of the hull. The housing features a water valve which minimizes water ingress into the boat when the retractable insert is being replaced with the blanking plug.
Airmar's Smart™ Sensors have embedded microelectronics. The signals from the speed and temperature sensors are processed right inside the housing itself. All that is needed to receive data is a single cable into a compatible network or display. Available as an analog sensor or a digital Smart Sensor that can output in NMEA 0183 or NMEA 2000 protocol.
