Bob gave you the right advice Doug.  There is a chance that the RMI sender
is compatible but without knowing exactly what it is I wouldn't advise going
there.

If you want more EM2 air temp sensors you can make them from the base part
which is the  LM34DZ  (for digikey part number add  -ND  ).   They are only
a couple of bucks each.  I can supply the same part with a few wires
attached and some heat shrink tubing around it but the price is way too high
:>)   The instructions for the wire colors and which leads are what color,
look in the back of the EM2 instruction booklet.  I added this sometime
during the past couple of years so let me know if you need updated
instructions.
