BS2i Industrial
Archiver
Posts: 46,084
Hi,
I am working onto some projec for an outdoor application, but even if
the winter is
done and we are supposed to be in spring, I'm in Quebec and it still -
19 degree
Celsius outside in the night time (last night) , so I've ordered from
parallax an
industrial version of a BS2 whish is the BS2i, i for industrial. No
doubt it will work
but I just (as curiosity ) would like to know the real difference
because both look
the same and the IC itself is not identified as an industrial version.
By the way, the
BS2 standard is supposed to be rated for only 0 degree but it still
worked fine
even at - 14 C, pretty good, but here, it still not enough.....
Thank you very much!
Rene

parts -- the PIC, the EEPROM, a few transistors,
and a resonator/oscillator. All the parts
must work at the low temperatures you're talking
about.
As is typical with electronic parts, if the vendor
certifies the part for a wider temperature range,
he has had to test them at that range -- and the
ones that fail at the wider range are sold as
normal parts.
Thus, you CAN have a 'lucky' selection of parts
that will work at the lower temperatures -- but
it's not guaranteed by the vendor.
That guarantee, and the extra testing are what
you are paying for when you buy the wider
temperature range part. In the case of the
BS2, ALL components have to be certified at
the lower temperature. Thus I think it's rare
to have a 'lucky' BS2.
