摘要： The temperature of an environment is determined by measuring the acoustical response of a temperature sensitive two mode resonator placed in the environment. Two variable frequency signals are generated and applied to the resonator, and the two resonant frequencies of the resonator are determined. Frequency difference of the two frequencies is determined, and if the difference lies within a substantially uniform frequency range, the environment temperature is calculated from at least one of the frequencies. If the difference lies outside of the substantially uniform frequency range, then at least one of the two signals is spurious and no temperature calculation is made.
