O2 Cell - Wich one

Nad · 31st May 2007, 09:10

Hi all,

I know that APValve sale the R22-2BUD that should be the same as the R22D. Any trouble to use the second? (Beside the fact that the factory sale and advertise his own specifics cell)

Thanks

Nad

They are the same cell - which are OEMd to AP.

I was under the impression that the -bud ones were retested to a higher set of tolerances and those not meeting AP's standards were returned.

NigelH disected a R22D and I disected a R22BUD, they were different, the BUD had an extra resistor.

There was probably a year or two between the times that we cut up these cells so they may be the same now.

There's also the warranty issue to consider - don't AP bin any non-BUD cells and replace them as a matter of course (or put new cells in if there are none) if you send the head back? That could easily demolish any saving you make by using Ds rather than BUDs.

Cheers,

Yes, absolutly.
But the question is if R22 D could be used in place of R22BUD.
I think that they are now the same, but...

I used R22 D's exclusively, never had a problem. Had all kinds of problems with the original R22BUD's. This was when they were having trouble with the coating on the boards (to be fair). Now trying out the AI sensors.........only have a few dives on them so too early to tell if they are better. However all three cells read exactly the same during calibration (at start and at the point of calibration)

Thanks everyone,
Phi your link was more than useful.

Best,
