Characterized by high reliability

visual operation principle

wide applications

stepper motor drving dam deformation monitoring instruments have been widly used in our country’s water conservancy proiects.However

many disadvantages such as poor accuracy

interference caused by long distance singnal transmission are still obvious.In order to solve these problems

a novel stepper motor driving dam deformation monitoring instrument is developed.The operation principle is elaborated.Owing to application of unique structure design and the latest electronic measurement lechniques

its performances are improved and the accuracy can reach ±0.1 mm

that makes it much more practical than ever.
