HEIGHT RECORDING SYSTEM COMPRISING A TELESCOPIC RULE WITH TWO ENDS COOPERATING WITH AN OPTICAL BEAM SCANNING IN A HORIZONTAL PLANE

摘要

A height recording system includes a telescopic rule formed from a head and a telescopic assembly used to vary a distance between one support end forming a base for the telescopic assembly and an upper end supporting the head. The height recording system comprises:a measurement system that measures the distance;a receiver including photosensitive cell(s) to detect an optical beam output from a laser system;a module starts or validates a height measurement by the measurement system starting the measurement or the validation in response to the module receiving a determined signal from the receiver; the determined signal being representative of the laser beam being detected by one of the photosensitive cells.
