The TS quartz temperature sensors are tuning fork quartz crystals
vibrating in a torsional mode. The crystals are designed so that their
frequency is both extremely sensitive to temperature and highly
linear. For example. the 172.0kHz design has a sensitivity of around
+46.4ppm/°C. This high sensitivity enables the detection of fine
temperature changes, the degree of which is dependant upon the
implementation. Further, this frequency-based technique has the
advantage of being immune to amplitude noise in the measurement
system, a feature not shared by thermocouple, thermistor or RTD
based temperature sensing techniques. Lastly, remote temperature
sensing is possible by using an antenna to pick up the frequency of
the EM waves emitted by the sensor.
