Measuring the height of valve housings
Task
After a valve housing is completely installed (plungers, seals, etc.) in an assembly device, it has to be checked for a height of 22.7 mm with a tolerance of +/- 0.1 mm.
Solution
After the valve housing is completely installed, its height is checked in a line laser fork light barrier with a tolerance of +/- 0.1 mm. The advantages of this solution are the accuracy due to the high resolution. There is no alignment, since the transmitter and receiver are in a rugged metal housing and the measuring method is independent of the various colors of the object.
