Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! Level is a measure of the height difference between the ground point of the instrument based on the principle of leveling. Water level is at 17 ~ 18th century invention of the telescope and the vial after appearing. Early 20th century, the production of micro-focus binoculars and pour water level in line with the standard within the system out basis. 20 appeared in the early 1950s automatic levelizer; 1960s developed a laser level; 90s electronic level or digital level. The application of different types of air damper compensator compensator Level, 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, but the compensation for post-inversion if subjected to more intense after the shock, the probability of hanging wire bending deformation due to compensation of failure is very high; Therefore, this compensation is widely used in middle and low water level automatic levelizer Price, rarely been applied to high-end equipment among. Desktop magnetic damping compensator Laser Level, 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.
