Development of a New Type Photoelectric Hydrostatic Leveling Instrument
Pages: 19-22
Year: Issue:  1
Journal: Dam Observation and Geotechnical Tests

Keyword:  linear light sourcelarge-scalehydrostatic levelingCCD;
Abstract: A large-scale hydrostatic leveling base on linear point light sources measurement is designed.Its principles,structure and control circuit are introduced,and the feasibility and reliability is verified by experiment.By using special float guiding device and a photoelectric sensor unit,to solve the problem of traditional photoelectric with complex structure,low degree of accuracy,poor reliability.The design not only solved the moldy of lens,also largely enhanced the measurement range, which using the linear point light sources.The instrument has been passed the type-test of the power industry and power system automation equipment quality inspection and test center,the indicators meet the design requirements.
