With the ST60 we get the opposit. 50 degrees F. Called Raymarine and they said it was common. Works on a relative increase basis (e.g identifying Gulf Stream) so we dont care about absolute numbers...

A few years ago during an offshore race, Touche's wind instrument indicated a steady 99 knots with gusts to 274 knots. After a power off/on cycle it indicated a more reasonable low 20's. :) Dennis C On Mon, Nov 30, 2015 at 9:28 PM, Russ & Melody via CnC-List <[email protected]> wrote: Hi Fred, Thanks for the link. I think maybe I should get one of my Instrument mechanics to see if they can come up with a value for the thermistor. Otherwise I might just grab a few and do it on a trial basis. When it first started failing, years ago, I mentioned it at a C&C rendezvous and got a "don't worry, it happens all the time" kinda response. I would like to credit Jim but now I can't be sure. And when the one on Amazing Grace went too I came to believe it is common. Or maybe the Strait of Georgia is responding well to the promise of global warming and really is 120.4 degrees :) Cheers, Russ Sweet 35 mk-1 B.C.

It’s just a thermistor potted in the transducer housing: http://www.airmartechnology.com/uploads/wiringdiagrams/91_636.pdf No info on the value of the thermistor... — Fred Fred Street -- Minneapolis S/V Oceanis (1979 C&C Landfall 38) -- on the hard in Bayfield, WI :^( On Nov 27, 2015, at 6:47 PM, Russ & Melody via CnC-List <[email protected]> wrote: Now, how about the unreliability issue with the temperature sensing element of the Raymarine transducer? Is it a simple RTD and of what value, so I can haywire something in stead of it? Cheers, Russ Sweet 35 mk-1 B.C.
