AT-Cut Thickness Shear Mode Piezoelectric Wafer for Downhole Oil Pressure Sensors
Introducing the piezoelectric quartz cap, an exceptional pressure sensor component that excels in performance and stability with its unique AT-cut quartz end cap design. Leveraging the principles of quartz crystal thickness-shear mode, this cap accurately senses applied pressure by monitoring changes in the crystal's resonance frequency.
Renowned for its outstanding frequency-temperature characteristics, the AT-cut quartz crystal ensures the accuracy and reliability of the sensor under various environmental conditions. The sleek and elegant end cap design not only enhances aesthetics but also facilitates seamless integration and installation within sensor components, offering users utmost convenience.
The working principle of the quartz cap is simple yet efficient. When pressure is applied to the quartz crystal, its mechanical stress and mass distribution undergo changes, resulting in a shift in the crystal's resonance frequency. This frequency shift is directly proportional to the applied pressure, enabling precise perception and measurement of pressure variations.
Whether in industrial control, environmental monitoring, or medical equipment, the piezoelectric quartz cap delivers outstanding performance, providing reliable solutions for your pressure sensing needs. Choose the piezoelectric quartz cap, choose trust and efficiency.
