.................Sikaflex, Tec7 or similar sealants as these products are super tough and adheres like crazy...............
Kinda what I was hoping for, given my suspicion that the original coating is so poor and appears to me to trap moisture and
cause corrosion - but point taken, especially in view of your comments regarding possible future repairs. I would hope that I can make a better job of it than the original poor effort.
..............After receiving the WG112 I noticed that there was a tracking number on the envelope. I didn't know that the shipment had tracking. That is nice. Did you get a tracking number?
Yes, I did and it arrived yesterday. A tracking number was referenced in one of the many emails from Ali Express. I'd taken it with a pinch of salt but it appears to have been reasonably accurate, even if only after the event, ie: 'Arrived at Import/Customs', 'At Delivery Depot', 'Out for Delivery'. The projected delivery date spanned a "20 - 39 days" period, never changed and it took 26. This repair project is a winter weather job on a non-functioning set of internals, so I didn't mind the relatively slow time delivery in view of the cost saving.
Regarding your new $10 oscilloscope, it may be useful for some applications. For some reason I had a hard time testing the performance of the new Wiegand sensor today using my good old Rigol DS1102E. I did not get consistent readings when rotating or swinging a magnet across the sensor. It may have been a oscilloscope setting problem or maybe I used a magnet that was not suitable. Even though the oscillocope readings made me think that the new WG112 was faulty, it actually works flawlessly
I'm not expecting a lot from it but the reviews mainly seem to criticise the high frequency measurements? - not a concern in our case, I think. Either way, it'll be interesting to compare notes when I get to try it.
I forgot to ask: have you successfully tried "the AA battery trick" to narrow the problem down to the WG112 sensor?
Short answer: No. We are still flat out working on our house renovation - 1000 M
2 of concrete/paving block driveway plus many other repair/replacement jobs - whilst the weather holds. All the information you and others have passed on is carefully stored and awaiting that rainy day. I for one am very grateful for it.
I suspect I'll be in need of quite a few indoor projects this winter since we normally head south and it probably won't happen this year due the Covid-19 situation, both here and in Europe. (please don't mention the added stupidity of the 'Brexit' situation, it's just too embarrassing
)
