Dimension measuring device

摘要

The system has positioning measuring probes i.e. axial displacement probe (40) and swivel arm probe (45), with a linear variable differential transformer sensor to provide an analog electric signal representative of variation of distance between the probes and a to be measured part (30). A wireless communication interface (80) connects the probes with a control unit. A digital processing unit is provided with a clock to control the unit and the interface. Clocks of the probes are programmed through the interface to program a measurement time in the probes.
