Calypso Ultra-Low Power Wired Ultrasonic NMEA2000 Anemometer

The Calypso Ultra-Low Power Wired Ultrasonic NMEA2000 Anemometer is a game-changer for sailors and boat enthusiasts.

Designed for effortless installation, this advanced wind speed and direction meter connects directly to any NMEA2000 network, chartplotter, or display without needing additional gateways or extenders. Utilising solid-state ultrasonic technology, the sensor is maintenance-free with no moving parts, ensuring long-lasting performance even in harsh marine conditions.

Perfect for racing and cruising yachts, powerboats, and sports keelboats, the Calypso Anemometer delivers accurate wind data you can trust.

Its compact, lightweight design makes it easy to mount on any yacht mast, providing reliable readings in all weather conditions. Whether you’re a professional sailor or a weekend adventurer, this anemometer is your go-to tool for precise wind monitoring.

• Direct NMEA2000 Connectivity: No need for output configuration; simply plug in and start using.
• Solid-State Ultrasonic Sensor: Maintenance-free with no moving parts, ensuring durability.
• Compact and Lightweight: Measures just 70mm x 70mm and weighs only 130-240 grams.
• Varied Mounting Options: Easy installation on aluminium, carbon fibre masts, or an offset L-shaped mount.
• Low Power Consumption: Requires only 0.25mA @1Hz (RS485), making it ideal for power-conscious boats.
• Robust Construction: Made from durable nylon polyamide, designed to withstand harsh marine environments.
• Accurate Wind Data: Delivers precise wind speed and direction readings, even in heavy rain.

Simply plug in the Calypso ULP Wired NMEA2000 Ultrasonic Anemometer directly into the NMEA2000 network (backbone) or chartplotter/display and choose Calypso ULP Wired NMEA2000 Ultrasonic Anemometer as the wind source in the chartplotter/display settings*, and then verify the wind data is appearing on your NMEA2000 display/plotter.

Installing the sensor is extremely easy and can be easily mounted to a yachts mast using varied mounting options including, aluminium and carbon fibre masts (33cm & 1m lengths) and an L shaped offset mast mount. Cables are available in 6m and 20m lengths and come complete with terminator for NMEA2000 backbone or chartplotter.

The ULP Wind Meter measures both wind speed (air velocity) and wind direction. The unique shape of the design minimises moisture build-up guaranteeing data accuracy even in heavy rain.
*The manner to do this will vary depending on the brand of the display/plotter. Please refer to your display/plotter’s manual.
