ZITN Fiber Optic Pressure Sensor is a high-performance measurement solution based on the Fiber Fabry-Perot (FP) interferometric principle. Engineered for demanding industrial environments featuring high temperatures, high pressures, and strong electromagnetic interference, it achieves precise pressure measurement by accurately detecting FP cavity length changes.
ZITN Fiber Optic Pressure Sensor integrates Fiber Bragg Grating (FBG) temperature compensation technology, ensuring high accuracy and long-term stability across all operating conditions and providing reliable data assurance for safety monitoring.
Application Areas
Oil & Gas: Downhole pressure monitoring, reservoir dynamic analysis.
Energy&Power: Internal pressure monitoring in high-voltage transmission equipment, transformers, and power generators.
Industrial Processes: Pressure monitoring in chemical reactors, oil/gas pipelines, and other flammable/explosive risk areas.
Geotechnical & Structural: Long-term pressure monitoring in geothermal wells, mines, and large-scale structures.
Product Features and Advantages
Exceptional Accuracy & Stability: Integrated Fabry-Perot pressure sensing and FBG temperature compensation design ensures high precision, long-term zero-point stability, and minimal temperature drift.
Intrinsically Safe & Highly Resistant: All-fiber, passive design makes it completely immune to electromagnetic interference and lightning strikes, suitable for hazardous areas.
Strong Environmental Adaptability: Operates stably across an extremely wide temperature range, with performance unaffected by light source fluctuations or fiber bending losses.
Remote Transmission & Easy Integration: Signals can be transmitted directly over long distances via optical fiber, supports simultaneous temperature and pressure measurement, and allows for simple integration and operation.
