Abstract: To deal with the interference signal produced by the tools of the communication in the workplace of the transmitter, a novel temperature measurement signal isolation transmitter has been designed and developed. This novel transmitter can reject the interference signal effectively with the differential amplifier and isolation amplifier. The test results show that the transmitter has high measurement precision, strong interference rejection capability and great engineering values.

Key words: Isolation transmitter, Temperature measurement, Interference rejection
