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

Motional characteristics
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
