Advanced fiber optic sensor features

With the development of optical fiber and optical fiber communication technology, the optical fiber sensor has sensing sensitivity many times higher than that of the traditional sensor, and it can work normally in many special environments such as high voltage, large noise, high temperature and strong corrosiveness. It can also cooperate with optical fiber remote sensing and telemetry technology to form optical fiber remote sensing system and optical fiber telemetry system. Optical fiber sensing technology is a high-tech that many economic and military powers are competing to study. It can be widely used in various fields of national economy and defense and military fields. Oil exploration (liquid level, flow measurement, etc.) in aerospace (pressure measurement, temperature measurement, gyro, etc. in various parts of aircraft and spacecraft), navigation (sonar, etc.), engineering projects (monitoring of bridge construction and restoration, railways, etc.) Measurement of voidage in two-phase flow), power transmission (current measurement of high-voltage transmission network, voltage measurement), nuclear industry (radiation dose measurement, leakage dose monitoring of atomic power station), medical (blood flow measurement, blood pressure and heart sound measurement), Scientific research (earth rotation, sensitive skin) and many other fields have been widely used. Therefore, our company represents a number of foreign professional manufacturers of fiber optic sensors such as: white Fabry-Perot interferometer fiber Sensor products, Bragg grating-type distributed and fluorescent fiber optic sensors and other related products to meet the needs of domestic counterparts.

Fiber optic sensors have the following main features:

· Free from electromagnetic interference (EMI) / radio frequency interference (RFI), corrosion resistance

·Applicable to aerospace, weapons, power, oil development, navigation, nuclear industry, medical and other fields

·Micro and rugged sensors

·small volume

·High temperature resistance

·High precision

·Intrinsically safe

·Packaging according to customer requirements

Fiber optic acoustic pressure sensors are characterized by high frequency response (30 kHz) and high sensitivity to detect small pressure changes even under the most unfavorable conditions. Designed for acoustics, microphones, motor vehicles, aerospace, aerodynamic applications or when it is necessary to use very sensitive pressure sensors.

The strain sensor has the characteristics of small size, high precision, anti-electromagnetic interference and radio frequency interference, corrosion resistance and wide operating temperature range. It has static/dynamic response, high sensitivity and high resolution (0.01% full scale). The influence of fiber bending affects the transmission of signals over long distances, and the absolute measurement of engineering units is suitable for mechanical engineering such as aerospace, construction engineering, bridge construction and maintenance.

Fiber optic gyroscope

Because it has a series of advantages such as large bandwidth, high resolution, good deviation stability and good shock and vibration resistance, it is widely used in various fields of national economic construction and defense equipment construction.
