A fiber optic pressure sensor is a measuring device that uses optical fiber as the sensing element to detect pressure changes. Its working principle is that when external pressure is applied to the optical fiber, it causes minute deformation in the diaphragm, cavity, or the fiber itself, thus affecting the optical signal within the fiber (changes in light intensity, phase, wavelength, or polarization). The sensor detects these changes in light and converts them into an electrical signal representing pressure.
Features of Fiber Optic Pressure Sensors
Strong anti-interference: Electrically insulated and immune to electromagnetic interference, suitable for hazardous environments such as flammable and explosive materials.
High precision and distributed measurement: Can monitor the health status of structures such as bridges and dams in real time, with a wide measurement range.
Portable and lightweight: Compact and flexible fiberglass, suitable for minimally invasive surgery and confined spaces.
Applications of Fiber Optic Pressure Sensors
Medical: Used for pressure monitoring of tissues or organs such as the cardiovascular system, intracranial cavity, airway, and gastrointestinal tract, enabling real-time analysis of lesions or intraoperative conditions. The FOP-MIV miniature fiber optic pressure sensor is professionally designed for medical applications and is widely used for pressure detection in various organs of the human body.
Industrial: Real-time health monitoring of bridges and dams; pressure detection in flammable and explosive environments.
Aerospace: Used in aircraft flight control systems, wind tunnel simulations, and other applications; offering a wide dynamic range, high accuracy, and the ability to withstand harsh conditions such as high temperatures and pressures.
