Product Description:
The gyroscope has a low power consumption at full temperature, consuming no more than 4 watts. This makes it energy-efficient and cost-effective to use. It also has excellent bias repeatability in different temperature ranges, with a range of less than 0.02 (maximum value minus minimum value). Additionally, it has a constant temperature bias repeatability of less than 0.001 at a constant temperature range of -40℃ to 70℃.
The dynamic range of the Fiber Optical Gyroscope is ±300, which means it can measure angular velocity accurately within this range. It also has a bandwidth of at least 200, which means it can measure angular velocity changes with a high degree of accuracy and precision. These features make it an ideal choice for use in a wide range of applications, including aerospace, robotics, and navigation systems.
The Fiber Optical Gyroscope operates using a process called the Sagnac effect. This effect is based on the principle that when light passes through a rotating medium, it experiences a phase shift. The amount of phase shift is proportional to the angular velocity of the medium. By measuring this phase shift, the gyroscope can accurately determine the angular velocity of the medium.
The gyroscope is also equipped with an accelerometer gyro sensor, which measures linear acceleration and rotation rate. This sensor helps to improve the accuracy and precision of the gyroscope, particularly in high-speed applications where small errors can result in significant inaccuracies.
Overall, the Fiber Optical Gyroscope is a highly advanced and precise sensor that is ideal for use in a wide range of applications. Its low power consumption, excellent bias repeatability, high dynamic range, and accuracy make it an ideal choice for use in navigation systems, robotics, and aerospace applications.
