Traveller30 1 Posted September 20, 2014 Report Share Posted September 20, 2014 Hi I'm using the NRG 200P wind vane for wind direction on the roof ofa building. Several days ago my sensor stopped working , so I opened it , andfound a lot of rust inside , I cleaned it up , but still the sensor not workingany more , it always gives me the same reading , 5V ,(I feed the power chordswith stable 5V) , I can?t understand whats gone wrong? Isaw a capacitor inside, it was rusted and not functional, but I can?t believe it?sthe reason, I think its purpose is to reduce noise. Anyideas what gone wrong? Iadded a photo of the open sensor https://drive.google.com/folderview?id=0BwE-Ba3ePCwOQWc3ZmJkdlRUd2s&usp=sharing Tnxin advance Roman JeremyNuh 1 Quote Link to post Share on other sites
David Carlson 7 Posted September 22, 2014 Report Share Posted September 22, 2014 I have attached testing instructions to this post: Testing200PVane.pdf.Testing200Pvane.pdf Have you performed these tests? The pictures you posted do show a fair amount of corrosion. If the sensor fails the tests in in the attached document the potentiometer may be damaged. The component you saw is not a capacitor, it is an ESD protection device to short all voltage spikes to ground. Quote Link to post Share on other sites
