TS Series Miniature Quartz Temperature Sensor 160 kHz to 350 kHz DESCRIPTION The TS Quartz Temperature Sensors are tuning-fork quartz crystals vibrating in a torsional mode. They are designed so that their frequency is both extremely sensitive to temperature and highly linear. For example, the 172.0 kHz design has a sensitivity of roughly +46.4 ppm/OC. This high sensitivity offers the ability to detect fine changes in temperature; the degree depending on 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.

(02, 03 & 04) 2) Take proper soldering consideration as the melting temperature of the lead-attach solder is 217OC. (06 & 07 only) FREQUENCY-TEMPERATURE MODEL Although the frequency-temperature characteristic of the TS sensor is nearly linear, it is not exactly so. A better model is a second-order polynomial in temperature: F(T) = F (T0) [1 + α (T - T0) + β (T - T0)2] While higher-order polynomial models are possible, a second-order model is usually sufficient. Taking T0 = 25OC, typical values for α and β are as follows: Frequency kHz 172.000 262.144 α ppm/OC 46.4 34.5 β ppm/OC2 0.036 0.018 HOW TO ORDER TS TEMPERATURE SENSORS TS2 TS1 = CX1 Leaded & SMD TS2 = CX2 Leaded & SMD TS3 = CX3 SMD only TS6 = CX6 SMD only S C “S” if special or custom design.
