ST30 wind - how does that work then?

Most wind transducers have rotating cups and a separate directional vane. My ST30 has a set of 3 cups and one of the cups has an extra tab on it, which presumably does the directional bit. There is no separate vane. It seems to work OK but I'm curious to know how. It just, you know - rotates , so how does it read the wind direction?

It rotates at an uneven speed...

The cups rotate at an uneven speed, speeding up when the cup with the tab is going away from the wind, and slowing down when the cup with the tab is going towards the wind. The electronics use these minute variations in rotational speed to work out which direction the wind is blowing from.

Check out the manual Here

Gives a full explanation.

Re: It rotates at an uneven speed...

Check out the paragraph on page 7 that's as full as I've seen... although your explanation is more concise /forums/images/graemlins/smile.gif

Oh right, where it says "The transducer, an innovative design (Patent pending) using an unbalanced anemometer to sense both wind speed and direction at the same time, can be mast or radar arch mounted to suit a wide range of vessels". That's a "full explanation" of how it works?

FFS PVB, it seemed good enough to me when you read the rest of the manual so chill out and back off, you answered as well so what's the problem?

No need to have a go at me if the answer wasn't full enough for you. What do you want a full thesis? I was only trying to help the guy, maybe he'd never seen the manual before? Maybe it'd help answer some more questions? Who knows! I was trying to help.

And people wonder why there are people who've been on these forums for ages with low post counts.
 
Re: It rotates at an uneven speed...

Thanks for that - haven't laughed so much for ages, Mr F. I just think it's astonishing how many questions on this forum are answered by posts with links, saying "look here for the answer" when it's patently obvious that the people replying couldn't be ar<span style="color:black">s</span>ed to check whether or not the answer is actually in the link they post. You did exactly that, and now you're getting uptight because I queried it. Maybe you should stick to the Lounge.
 
Re: It rotates at an uneven speed...

I find it astonishing that you are the one so uptight about it, why bother quoting the paragraph? why make a big deal out of it?

Get a life man, crowing about how you know more than others is really, really sad.

Your approach kills the spirit of forums, trying to help people is what the forums are all about, discussion, sharing of ideas not banging on about how much you know and if you don't know don't bother posting.

Do you know how childish that is?

It's not that big a deal posting a link to a manual or even heaven forbid not the exact answer to the question.

Maybe you should get out more, mix with humans, even visit the lounge or scuttlebutt... loosen up you know?

Exactly my point! If you don't know the answer, it doesn't help at all to waste people's time by posting links which don't answer the question - it doesn't help anyone. And, with the greatest respect, maybe it's you who needs to loosen up a bit. /forums/images/graemlins/wink.gif
 
Re: It rotates at an uneven speed...

Oh come on now fellas, don't get all het up over nothing, you're spoiling my thread and maybe discouraging others from joining it. Thanks for bothering to answer. I have the manual and had read the paragraph mentioned, but curiosity demanded a more thorough explanation of how it works. After all, this unit has one less moving part to go wrong, so if it's so clever why don't other manufacturers use the same principle?
 
The clue is...

[/ QUOTE ]Think the clue is in that little phrase "patent pending"! It's certainly a clever idea, a friend of mine fitted one and says it works well.

[/ QUOTE ] "Patents pending" - so they can't nick the idea?

Only a matter of time before someone else finds a way to do the same thing without infringing the design patents.
