ABSTRACT:
A height measuring device comprises a carriage containing a measuring pin which is moved by a drive motor against an article to be measured in a manner such that the measuring takes place when the pin is held against the article with a precise measuring force. The construction includes a carriage which is supported by an endless belt and moved upwardly and downwardly by driving one of the rollers over which the belt is guided. A ram rod extends through a hollow area of the carriage which is divided by a ring piece into upper and lower chambers, the coil springs are placed around the ram rods in both the upper and lower chambers and are braced between the ring pieces at their one ends and the portion of the carriage which closes each end of the hollow portion of the carriage. The drive motor for moving the carriage is controlled by a control which ensures that the movement for urging the measurement in against the article will always take place at a selected measurement pressure between the pin and the article to be measured.
