HIGH-TEMPERATURE SENSING QUARTZ CRYSTAL RESONATORS
RKTV206 and RKOV206
APPLICATIONS
RKTV206 used to sense temperature changes. It is designed for applications in
precision electronic thermometers and temperature controllers for the conversion of
temperature to frequency. RKOV206 is a temperature-stable reference quartz crystal
resonator.

Thermal characteristics
Frequency Vs. Temperature fT=fO +A1*(T-TO) +A2*(T-TO)2,
where: fT – crystal frequency at temperature T (°C),
fO – crystal frequency at reference temperature TO (°C),
TO – reference value of temperature (°C).
For higher accuracy a third order polynomial is recommended as follow: fT=fO +A1*(T-TO)+A2*(T-TO)2+A3*(T-TO)3

For high-temperature sensing, the crystal RKTV206(A…C) is used in combination with the temperature-stable reference crystal
resonator RKOV206(A…C). The frequency difference between both is used as temperature signal.
