Welcome to inquire! Contact: Li Yongjie. The application of different types of air damper compensator compensator Level Company, subject to environmental surrounding magnetic field is small, but because of the complexity of the assembly process more used not yield, high precision automatic levelizer. Cross-type magnetic damping compensator, the assembly process is simple, part accuracy requirements are not very demanding, low cost dsz2 water level, but the compensation for post-inversion if subjected to more intense after the shock, since the hanging wire bending deformation caused by the failure probability is very Compensation high; so this compensation is widely used in middle and low auto levelizer, but is rarely applied in high-end equipment among. Desktop magnetic damping compensator Level check, the assembly process is relatively complex, component requirements are relatively high, the cost is relatively high, but because of the earthquake than other compensation, and more are applied in high-end automatic levelizer. Cross-calibration error compensator placed in the instrument calibration stage, adjusting the center circle blisters and leveling the instrument, the instrument is within the range of tilt compensation equipment (even if the instrument left or right high low high low left and right), at this time if the instrument reticle crosshairs above or below the target crosshairs, then prove that the instrument has cross errors can be corrected by adjusting the compensator on the side of the left and right sides of the two small screws until they adjusted to within the allowable range
