Delay line and oscillator temperature sensors are fabricated using YZ-LiNbO3 single crystals and (110) <001> -Bi12GeO20 single crystals. The center frequency of the experimental device is between 20 and 55 MHz with a relative sensitivity of 80 to 115 ppm / ° C. The measured frequency-temperature characteristic curves are given and have a good linear relationship in the temperature range of -40 ~ + 85 ℃. The output is digital information and can be processed directly. This type of sensing device is extremely promising for temperature telemetry and remote control.
