Temperature sensor ST850SS-2000

speedfor boatNMEA 2000®

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. Speed and fast-response water-temperature sensing Speed range: 2 to 45 knots (2 to 52 MPH) NMEA 2000 protocol Retractable insert in a low-profile housing with a water valve Available in a plastic (P17) or bronze (B17) housing Retrofits into B617V, P617V, SS617V, P217, P314, or ST650 housing NMEA 2000 certified cable Functions: Speed, Temperature Mounting Style: Low Profile Thru-Hull Power Rating: N/A Protocol Output: NMEA 2000® Housing: Stainless Steel Hull Material: All hull materials Hole Size: 51 mm (2") Retractable housing: Yes Cable-Length: 6 m (20') NMEA 2000® cable Common Use: Cruising/Racing Sailboats, Leisure/Yachting, Fishing Data Rate: 1X per second Pulses: 17,000 p/nm* (4.8 Hz per knot)—*p/nm = pulses per nautical mile Retrofits: Retrofits into B617V, P617V, SS617V, P217, P314 or ST650 housing
