circuit to use GM temperature sensors for voltage based data acquisition input?

[bcroe at juno.com]

Jason, Can you give me the sensor resistance at the 
temperature you want 10 volts out, and for zero volts, 
and a few points in between?  If so, I might be able to 
cook up an op amp circuit to do it.  12v supply ought 
to work if it is clean.  If not regulated, another voltage
reference will be needed
