The ST850 is a low-profile, retractable, thru-hull sensor that computes accurate speed and temperature data and sends it to any NMEA 2000network. These low-profile units are nearly flush, minimizing drag with only 5mm (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 SmartSensors 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.
