CV7-C-RM – High speed ultrasonic wind sensor for rotating mast

Combination of the CV7-C wind vane-anemometer for racing and the RM-CANBUS calculator – NMEA2000® interface for rotating mast, compatible with the SMART position sensor.

SKU: CV7-C-RM_M Categories: ,


Set of racing instrument that includes the CV7-C and the RM-CANBUS interface (Rotating Mast), which is an NMEA2000® rotating mast calculator with integrated barometer.

The CV7-C is a wind vane-anemometer that operates 2 times faster than the CV7 and CV7-V. The CV7-C-RM Pack is compatible with the SMART mast angle position sensor which allows for very accurate control of movement and improved operational efficiency and safety. It detects the position of a magnet relative to the sensor.
