rk206

  APPLICATIONS
RKT206 used to sense the change in temperature. The crystal designed for function as a component of the precision electronic thermometers and temperature controllers for conversion the current values of temperature to frequency.

- High shock and vibration characteristics
- Miniature size
- Wide temperature range (-50…+100 °C)
- Low power consumption
- Suitable for DTCXO and temperature equipment

Motional characteristics

Frequency vs. temperature fT=fO +A1*(T-TO) +A2*(T-TO)2,
There: fT – crystal’s frequency at current value of temperature T (°C),
          fO crystal’s frequency at reference value of temperature T (°C),
        TO – reference value of temperature (°C).
For getting of the greater accuracy a representation value of fT by a polynomial of the third order and definition of factor of the third order is possible as follow:
fT=fO +A1*(T-TO)+A2*(T-TO)2+A3*(T-TO)3
