Description
The ST850 is a low profile, retractable, thru-hull sensor that computes accurate speed and temperature data and sends it to any NMEA 0183 or NMEA 2000® display or network. These low profile units are nearly flush and minimize drag with only 5 mm (3/16 in) extending outside of the hull. The housing features a water valve which minimizes water ingress into the boat when the retractable insert is temporarily out for cleaning. Airmar’s Smart™ Sensors have embedded microelectronics – the transducer element and signal processor are only millimeters apart. The signal from the depth transducer is processed right inside the sensor itself. All that is needed to receive depth and temperature 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® format.
