The nke Ultrasonic Speed Sensor measures speed and distance covered, as well as water temperature. Its ultrasound technology allows it to achieve a level of accuracy and reliability superior to standard paddlewheel speedometers. In the absence of any moving mechanical parts, no maintenance is required once installed and antifoul paint may be applied. Fitting flush to the hull, it does not affect boat speed. It is connected to the system via the nke Speed/Depth Interface and is supplied with a moulded connector and 10m cable.

This unit is compatible with all nke installations and most others: paddle-wheel output at 4.5 Hz/Nds and NMEA 0183 output: VHW

Dimensions compatible with 1.8' and 2' housings (31mm and 40mm internal diameter).

Installation kit 31-35-001 includes through-hull housing, plug and grease (not supplied).
