In order to realize linear output of Z-temperature sensor
the circuit of Z-temperature sensor is designed based on the actual test and research about the property of Z-temperature sensor.The output standard value of temperature digit sensor is given.The nonlinear compensation is realized by the method of fraction linearization through monolithic microcomputer program.The experimental results show that the maximum error between the output of designed Z-temperature sensor and the expected linear output are less than ±1 ℃
