Abstract: In order to solve the problem that the measurement accuracy of dew point transmitter is affected by the change of ambient temperature，the mechanism of the influence of ambient temperature change on the accuracy of dew point transmitter is analyzed,combined with the existing dew point transmitter based on double resonant humidity sensor,a temperature compensation method based on adaptive partition fitting curve is proposed,and then test and verification is conducted.The test results show that the environment temperature adaptability of dew point transmitter could be effectively improved through this method.

Key words: Dew point transmitter, Quartz resonant, Temperature compensation
