In recent years, the sensor is sensitive, accurate, adaptable, compact and intelligent direction.In this process, the acclaimed new family of fiber optic sensors this sensor.Optical
fiber has many excellent properties, such as: the performance of the
anti-electromagnetic interference and atomic radiation, the diameter of
fine, soft, light weight and mechanical properties insulation, the
electrical performance of the sensor water resistance, high temperature,
corrosion-resistant chemical propertiesto
reach places (such as the area of the high temperature zone), or
harmful to people (such as nuclear radiation zone), it can play the role
of people's eyes and ears, but also beyond the physiological limits of
human senses ofsensor supplierthe recipientnot feel the outside information.
The fiber optic sensors is the emergence of new technologiessensor distributorin recent years can be used to measure various physical quantities, such as the sound field, electric field, pressure, temperature, angular velocity, acceleration, etc., you can also complete the existing measurement techniques difficult to complete the measurement tasks.In a small space in the environment of strong electromagnetic interference and high-voltage, fiber optic sensors have shown a unique ability.Fiber optic sensors have been more than 70 kinds, broadly divided into fiber-optic sensors and optical fiber sensors.
The so-called fiber-optic sensors, optical fiber itself directly receive outside measurement.External measurement of physical quantities can cause changes in the measuring arm length, refractive index, and diameter, allowing the transmission of light in the fiber changes in amplitude, phase, frequency, polarization, etc..Measuring light and reference arm of the arm transfers the reference light interfere with each other (comparison), the output of the light phase (or amplitude) changes, this change can be detected in the measured change.Phase by the outside influence of the high sensitivity of optical fiber transmission, the use of interferometry to detect the small phase change of 10 to the minus fourth power of curvature of the corresponding physical quantities.Fiber winding and low loss can be a very long optical disc into a small diameter fiber optic ring in order to increase the use of length, the higher the sensitivity.
The fiber-optic acoustic sensor is a fiber sensor.When the fiber is very small external force, it will have slightly curved, and its ability to pass light to change a lot.The sound is a mechanical wave, the role of its fiber is the fiber force and bending by bending on the strength of the sound.Kind of fiber optic gyroscope is also a fiber optic sensors, laser gyro, fiber optic gyroscope with high sensitivity, small size, low cost, can be used in aircraft, ships, missiles and other high-peazrformance inertial navigation system.Figure is the principle of fiber optic sensor turbine flowmeter.

In addition, a major category of fiber opticsensor dealeruse fiber optic sensors.Its structure is as follows: the sensor is located on the fiber end, the only optical fiber transmission line, the physical transformation to become the light amplitude, phase or amplitude changes will be measured.In this sensor system, sensors and fiber combined.The import of the fiber makes the telemetry probe of the possibility.Of this optical fiber transmission sensors are suitable for a wide range of easy to use, but the accuracy is lower than the first sensor.
Fiber optic sensor family is a rising star, which by virtue of the excellent performance of the fiber has been widely used, a sensor is worth noting that in the production practice.

Nice information. Fiber optic sensors are ideal for hard conditions including high vibration, extreme heat, noisy, wet, corrosive or explosive environments. Fiber optic sensors are small enough to fit in confined areas and can be positioned precisely where needed with flexible fibers. It can play the role of people's eyes and ears. SWOT Analysis
