   I heard that YSI makes a "linearised thermistor", which is a thermistor
   packaged with a resistor network in such a way that the resulting resistance
   is linear with temperature.  Does anyone know what this resistor network
   looks like?    Robert Enenkel (enenkel@na.toronto.edu)

I don't think that it is that easy.  The linear temprature transducers
I have seen were active devices, I think.  Not only the thermistor but
some kind of log amp and network that compensated.  It was still
convenient and the size of a small transistor.
