Airmar ST850 NMEA2000 Speed Tranducer

Airmar’s ST800 and ST850 Smart™ Sensors feature embedded micro-electronics. Speed and temperature signals are processed inside the sensor and can be displayed on any radar, chart plotter, or device that accepts NMEA 2000® data.

The ST850 is Airmar’s standard, thru-hull, speed and temperature sensor. The plastic, bronze, and stainless steel outer housing options are available to meet all hull requirements. These low-profile housings are nearly flush and minimize drag with only 5 mm (3/16”) extending outside the hull.

  • Speed and temperature

  • Retractable plastic, bronze, or stainless steel housings with valve sleeve

  • ST800—Retrofits into Airmar P120 and B120 housings

  • ST850—Retrofits into Airmar P17 and B17 housings

  • 6 m (20’) NMEA 2000 cable w/ Devicenet connector

  • Speed Range: 2 knots to 45 knots (2 MPH to 52 MPH)
