High Precision CQRPS01-1 Quartz Resonant Pressure Sensor

The full temperature uncertainty of quartz resonant pressure sensors can reach 0.005% FS, with laboratory uncertainty as low as 0.001%. Due to the excellent mechanical resonance characteristics of quartz crystal material, quartz resonance represents the future development direction of ultra-high precision and miniaturized pressure sensors. Quartz resonant pressure transmitters offer higher frequency stability and temperature stability, maintaining high-precision measurements in harsh petrochemical working environments. They also feature good long-term stability and strong corrosion resistance, making them more suitable for accurate and reliable pressure measurement and monitoring under complex and severe conditions in the petrochemical field.

A high-precision pressure sensor that uses quartz crystal material as the sensing unit to detect pressure changes. Compared to metal-based and ceramic-based pressure sensors, it has the advantages of small size and high integration; compared to silicon-based pressure sensors, it offers lower temperature drift coefficient and higher stability.
