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.
FEATURES
- High shock and vibration characteristics - Miniature size - Wide temperature range (-50…+180…+ 370 °C) - Suitable for DTCXO and precision temperature equipment ELECTRICAL CHARACTERISTICS (at 37 °C) / OPERATING CONDITIONS PARAMETERS SPECIFICATIONS AND REMARKS UNITS Electrical characteristics at 37 °C Frequency Range, fO 32.000…36.000 kHz Frequency Tolerance typ./max., ∆f/fO ± 150 ppm Resonance resistance typ./max., Rr 75/95 k Ω Static Capacitance typ., CO 1.3 ± 0.2 pF Capacitance ratio r, typ. 900 Drive Level max., DL 3.0 µW Insulation Resistance min. 500 M Ω 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 Model RKTV206A RKTV206B RKTV206C RKOV206(A…C) 2nd order temperature coefficient A2* -0,00310 ± 0,0001 -0,00310 ± 0,0001 -0,00310 ± 0,0001 -0,00120 ± 0,0001 K -2 Reference temperature 0 25 ± 5 °C 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.
