It has high temperature control accuracy and rapid cooling or heating, which can meet the requirements of the fiber optic gyroscope system.

[0005] Although the above-mentioned existing fiber optic gyroscope constant temperature equipment has a constant temperature function, its overall convenience is poor and it needs to be placed manually, which makes it inconvenient to use and has low efficiency, and is not conducive to use in automated workshops; therefore, it does not meet existing needs. We have proposed a constant temperature device for fiber optic gyroscopes. Utility Model Content
