Probe head operative in all directions - for performing measurements on machines, consists of bar brought in contact with surface to be tested

摘要

The measuring apparatus includes a movable element which is connected with the bar, and there is a fixed support for this movable element; these two components have contacts which form together a switch with at least one contact. The position of stable equilibrium of the movable element relative to the fixed support is statically determined, without excessive limitations; the switch is closed only in this position of stable equilibrium. The apparatus has a cylindrical housing (1) and there are three rods (3) at its lower end, which are fastened with screws (4) to an end block (5) which has a conical central bore through which the probe (24) passes.
