Abstract
Thermistor is one of the passive sensor based on the change of resistance value toward the heat change. The respond nonlinearity of thermistor against the heat change has been the weakness of this sensor, but this thermistor has high sensitivity up to 2,43 dT dR Kohm/K. The signal condition series is realized by the use pf two op-amp series which was cascade arranged in order to minimize the internal noise in the level of strengthening. Bu using once strengthening as well as high strengthening will multiple the noise value as much as Atime of strengthening. The result of the design used to measure the rock heat showed that there was an agreement between the result of the measurement and the reference value in the rock which was given by Gretener1) .
