Abstract
An exemplary distance measuring probe (100) includes a tube track (12), a tip extension (16), a pair of hollow tubes (14), a pair of air discharge systems (115), a linear measuring scale (18), and a displacement sensor (19). The tip extension is configured to touch a surface of an object (50). The linear measuring scale and the displacement sensor are respectively fixed relative to one of the tube track and the tip extension. The hollow tubes contain a flux of air, and are configured to cooperatively push the tip extension to move. Each air discharge system ejects part of air in the corresponding hollow tube out of the hollow tube. The linear measuring scale displays values of displacements of the tip extension. The displacement sensor detects and reads the displacement values displayed by the linear measuring scale.
