Weems & Plath Tamaya Marine Vane (Analog)
The KV-5020 marine wind vane/anemometer is for use on ocean-going vessels. It sends both wind direction and speed signals simultaneously from the transmitter for remote observation.
The transmitter is a propeller/windmill type and is used in combination with the wind speed/direction indicator. The analog indicator receives and processes the transmitter signals to drive the pointers.
Features:
- Two-piece system – vane transmitter & analog indicator
- Built-in NMEA(National Marine Electronics Association) output, indispensable for ocean-going vessels
- VDR compatible
- Stepping motor-driven pointers resistant to vibration offer a reliable indication
- LED illumination with dimmer
Optional Add-Ons:
- A digital indicator that accommodates signals of your choice
- KV-5025 - Simplified vessel speed/course signal transmitter (using GPS/magnetometric sensor)
- Additional indicators
