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 :)

This is the first one Iâve heard of that
failed. Usually theyâre very
reliable. Itâs just a thermistor potted in the transducer housing:

No info on the value of the thermistor...

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?
