1. Product Overview
HGFOCS fiber optic DC current sensor is a new type of sensor based on Faraday magneto-optical effect. Its foundation is fiber optic gyroscope technology. Its reliability and stability have been tested for a long time. Our company has jointly developed HGFOCS fiber optic DC current sensor with domestic experts in related fields. It is a new type of current sensor integrating microelectronic technology, network communication technology and optical technology. The product has been widely used in electric power, electric smelting, electrochemistry, high-speed rail and military aerospace fields.
Optical fiber DC current sensor has the following advantages:
1, high precision, good stability: the use of fiber optic gyro full digital closed-loop feedback signal detection scheme, with high precision and stability.
2. Large dynamic measurement range: The optical fiber DC current sensor uses magneto-optical materials to sense the magnetic field, and there is no magnetic saturation phenomenon. Therefore, the optical fiber DC current sensor has a large dynamic measurement range and can still ensure accuracy under overload conditions.
3. Strong anti-interference ability: According to Ampere's law, it can be known that the current value of the optical fiber DC current sensor is the current in the sensing ring, which avoids the interference of the external magnetic field.
4. Light weight and convenient installation: The entire optical fiber sensing unit is composed of a skeleton and a sensing optical fiber, and the light weight can be installed on any part of the conductor
5. The output signal is diverse: the output signal has digital signal and analog signal, which is convenient to interface with the user
6. Strong functionality: real-time monitoring and display of measured current and voltage values; Cumulative value of current and voltage in hours; Electrical parameters such as power and electric energy value
