| Abstract: | A precise digital thermotransducer with hish Q value quartz crystal is recommended. There is a good linear relation between the frequency and temperature in large measuring scale and high resolution. Its main benefits are good resistant to interference and digital output. Also a measuring system is described in this paper which is made of micro-chip computer.It processes the frequency signal of the thermotransducer,converts the digital value,displays the data and controls the printer and remote distance transmission.The system can be used not only in under-land temperature measurement,but also in the circumstance temperature measuring of hish precise industrial processing. |
