ABSTRACT:
A linear measuring device (10) and method for measuring the length of an element along an axis thereof includes a shaft (12). A first end block (14) supports one end of the shaft (12) and a second end block (16) supports the other end of the shaft (12) in spaced relationship to a support surface. A linear scale (18) interconnects the end blocks (14, 16) along the length of the shaft (12). A slideable block (26) is supported by the shaft (12) for moving along the length of the shaft (12) to measure the length of the element with respect to the first end block (14). A detector head (82) and display counter (84) provide a linear displacement of the slideable block (26) measured along the linear scale (24).
