ABSTRACT:
An omnidirectional electronic probe indicating the fall out of balance position, and particularly suitable to be used in measuring machines, is described. This probe comprises a rod arranged to come into contact with a surface to be inspected, a movable body connected to the rod, and a fixed support body for the movable body; the fixed and movable bodies comprise electric contact elements which provide in combination a switch. The main feature of this probe is that the stable balance position of the movable body with respect to the fixed body is a statically determined balance position and the switch is closed exclusively for the unique stable balance position. Another feature of the probe is to be provided with miniaturized electronic circuits which prevent the transmission of erroneous signals to the machine during the phases of opening and closure of the switch.
