Thermistors are available in Linear and Non-Linear varieties;
Non-Linear thermistors are typically two-wire sensors that have
resistance vs. temperature charecteristics
that are non-linear over their temperature range. These thermistors
follow the Steinhart-Hart Equation and a set of constants to calculate
temperature from their resistance. These thermistors are typically
used with electronic instruments that contain circuitry set up specifically
for the thermistor, or in a voltage devider circuit.
Linear thermistors are typically 3-wire devices with two individual
thermistors in one package. When combined with specific series
and shunting resistors, these sensors provide an output that is linear
over a specific temperature range. These are typiclally used in
Thermistors are typically used in applications where their large
changes in resistance per degree allow for precise measurement
of small temperature changes. This feature also provides the user with
better resolution than do Thermocouples which change a few millivolts
per degree or RTDs which typically change less than ½ of an ohm per degree.

and application information on Thermistors.
