<p>Yes. Sensors must be resistive elements, capable of taking 9 volts in
either polarity (in case they're connected "backwards") and may
present a resistance of anywhere from 0 ohms to infinity.  The
effective useful range is from 0 to about a million ohms.  It's linear
from 0 to 10,000 ohms, then starts to go exponential.  A resistance of
10,000 ohms gives a reading halfway between 0 and 1000 (which is the
reading for infinite resistance). A detailed table is at: </p>
