Nano-Resolution TechnologyInherently digital sensors based on quartz crystal technology are usedextensively for environmental monitoring because of their highabsolute accuracy and long-term stabilityMany oceanic, atmospheric and seismic applications requirebroadband, high-resolution measurements of dynamic phenomenaAdvances in counting circuitry and digital signal processing haveimproved the resolution of Quartz Crystal Resonator Sensors to asensitivity of parts-per-billion over an extended spectrumParoscientific, Inc.
Advantages of Quartz Resonant Sensors• High ResolutionMore precise measurements can be made in the time domain thanthe analog domain.• Excellent AccuracyThe quartz crystal sensors have superior elastic properties resultingin excellent repeatability and low hysteresis.• Long Term StabilityQuartz crystals are very stable and are commonly used as frequencystandards in counter-timers, clocks , and communication systems.• Low Power Consumption• Low Temperature Sensitivity• Low Susceptibility to Interference• Easy to Transmit Over Long Distances• Easy to Interface With Counter-Timers, Telemetry, and DigitalComputer SystemsParoscientific, Inc.
