ST800 ST850 Thru-Hull Speed & Temperature Smart™ Sensors Features • Speed and temperature • NMEA 2000® or Analog output options • 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, 9 m (30’) Analog cable • Devicenet connector or NMEA 2000 version • Speed Range: 2 knots to 45 knots (2 MPH to 52 MPH) The Smart Alternative! Airmar’s New 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. Minimize Your Drag 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. Eliminate Turbulence The plastic P217 and bronze B119 countersunk flush outer housings are easy-to-install. The plastic P314 and bronze B21 outer housing options have a traditional beveled-edge for flush mounting. Flush-mount housings eliminate turbulence for accurate readings at high-speeds. They are the optimal choice for installation in racing sailboats and high-speed powerboats
