FAQ
Q: What is a quartz resonator used for?
A: Quartz resonators are used in precision applications requiring stable frequency control, vibration sensing, or specific resonant characteristics. In electronic applications, they control oscillator frequencies. In mechanical applications like our quartz hemispherical shell resonator, they function as the core sensing element in gyroscopes and inertial measurement devices for aerospace, navigation, and precision instruments.
Q: How does a quartz resonator work?
A: Quartz hemispherical shell resonators utilize the principle of mechanical resonance in precisely shaped structures. When excited at their natural frequency, these resonators vibrate in specific, predictable patterns. Any rotation of the resonator causes shifts in these vibration patterns due to the Coriolis effect, which can be measured to determine angular velocity and position. The extremely stable mechanical properties of high-purity quartz allow for exceptionally accurate and drift-resistant measurements.
Q: What are the applications of quartz glass resonators?
A: Quartz glass resonators are used in numerous high-precision applications including:
1) Aerospace navigation systems and inertial measurement units;
2) Hemispherical resonator gyroscopes (HRG) for satellite stabilization and aircraft navigation;
3) Scientific instruments requiring precise frequency control;
4) Seismic sensors and vibration monitoring equipment;
5) Precision timing devices;
6) Advanced optical systems and resonant cavities.
Q: What are the advantages of fused silica resonators in high-temperature environments?
A: Fused silica (high-purity quartz) resonators offer several advantages in high-temperature environments:
1) Exceptional thermal stability up to 1600°C;
2) Very low coefficient of thermal expansion (0.5×10⁻⁶/K), maintaining dimensional stability;
3) Resistance to thermal shock; 4) No phase transitions that would affect performance;
5) Maintained mechanical properties at elevated temperatures;
6) Chemical stability even at high temperatures, preventing contamination or degradation.
Q: How do I determine the right specifications for my quartz resonator application?
A: Determining the right specifications involves considering factors like operating environment, precision requirements, resonant frequency needs, and mounting constraints.
