Non-mechanical Wind Transducers
I thought I'd ask the group for any experiences with non-mechanical (no
bearings, roating cups etc) wind transducers. The technology seems reasonably well established (ultrasonic, heated wire etc) in commercial and military applications and there are a couple of ones with NMEA output as well as one with Seatalk as an output option. Has anyone had any experience good, bad or indifferent with them and are there any reliability issues with them? -- Regards, John Proctor VK3JP, VKV6789 S/V Chagall |
Where to see the Seatalk one option?

Raymarine makes one. I assume it speaks SeaTalk.

No movig or wearing parts. -On ships and in weather stations etc. this technique has been used for some time. -The ROWind would be very hard to calibrate when connected to most instrument systems. One would have to go up in the mast and rotate the transducer to get the thing calibrated. -Most advanced (I don's know any that wouldn't) instrumet systems needs propriatery wind transducers in order to be able to calibarte them from the display. Also I do not know what would happend to the true wind, one would probaly not get that. Regards, TomS |
Raytheon offered one when I ordered my last set of instruments about
5 years ago. That was when I worked for Raytheon before they became Raymarine though. Doug s/v Callista "John Proctor" wrote in message news:2005010720584116807%lost@nowhereorg...

OK? I've seen both used on both. What's your point?

Have Raymarine also a Non-mechanical Wind Transducer?

Has anyone had any experience good, bad or indifferent with them and are there any reliability issues with them? Discussion seems to be a little off topic. Obviously nobody is using one or has direct experience. Summary: Raymarine in spite of what Doug says does not have a non-mechanical transducer for sale. If so part no please! Certainly nothing on their web site. Non-mechanical transducers are used in a number of commercial/military applications but not prevelant in recreational boating. My application is for a wind system to fit im with my Raymarine ST60 system. I have seen enough dud mechanical transducers to not want them on my boat. Therefore I'll wait. -- Regards, John Proctor VK3JP, VKV6789 S/V Chagall |
They did when I worked for them.

Thanks for your explanation.
As motoryacht owner wind speed is more important as direction.
