The columnsyn sensor is a new type digital linear displacement sensors. It rooted from conceive of improvement of linearity synchronization. The accomplishment of conception prototype’s research and manufacture verified the design idea is correct and reasonable. Based on the whole continuous windings structure

the columnsyn sensor can completely remove the head effect which is inherent in group windings. The experimental prototype has been designed and manufactured and has past many related tests. The test results showed that the experimental prototype has good space orthogonality

and the measurement system error is small. It can be used for the fine displacement measurement. The basic structure of experimental prototype of columnsyn sensor are introduced and the columnsyn sensor’s working function and performance are verified.
