TEMPERATURE SENSING QUARTZ CRYSTAL RESONATOR RKT206
APPLICATIONS
RKT206 is a quartz crystal resonator used to sense temperature changes. The
crystal is designed for precision electronic thermometers and temperature
controllers for conversion of temperature to frequency.
FEATURES
- High shock and vibration characteristics
- Miniature size
- Wide temperature range (-50…+100 °C)
- Low power consumption
- Suitable for DTCXO and temperature test equipment

Frequency vs. Temperature fT=fO +A1*(T-TO) +A2*(T-TO)2,
There: fT – crystal frequency at temperature T (°C),
fO – crystal frequency at reference temperature T0 (°C),
TO – reference temperature (°C).
For higher accuracy fT can be represented by a third order polynomial as follow: fT=fO +A1*(T-TO)+A2*(T-TO)2+A3*(T-TO)3
1st order temperature coefficient A1*
2nd order temperature coefficient A2*
