Optrel Satellite Evolution, must be pushing 20 years old... I like it, I know some on here don't... always kept on top of a cabinet facing a window so gets lots of bright light.
Wore it to reweld some of my late old man's handiwork on a garage door (sorry dad) and realised it wasn't darkening. Thought I could see the weld quite well
Anyway, fannied about with it and could hear almost a relay click inside the thing (which would seem unlikely) as it went dark, when lifted to sunlight. OK, so let's leave it in the sun for a few hours.
Tried it again and could get it to go dark but then it wouldn't clear in reduced light! WTF?
Then I realised that it went dark if my hand was over the sensors, and cleared in light. WTAM-FF?!
OK, I thought, off to Google for a new module. Er... not a chance.
Right then, maybe the batteries have died, I mean it wouldn't altogether be a surprise after all this time.
So I got all surgical with an X-Acto and removed an area of the cover to expose the batteries (2 CR2330s), prised them up to get meter probes in and... 3.06, 3.08V. Shorted them out to pull the voltage down and it quickly came back up to the same reading. So maybe the batteries aren't kaput. But for the sake of a fiver I'll change them anyway and see what happens. Could be the 'click' is actually something breaking down, arcing, probably terminal (no pun intended
)
If all else fails I hear Lidl offer lids for £25... even at one a year for ten years that would see me into my 70s and be less than a new Optrel

Alternatively maybe just source a different module, I think they're much of a muchness dimensionally - the lid itself is in good shape and I have a plentiful supply of the outer lens...
