It is movable through an angle drive by the sensing pin. A dial gauge is mounted at the tube end. It has a lever type indicator, an electronic or pneumatic sensor etc.. The angle transmission has a driving rack on the sensing pin, a driven rack transversal to it and a guiding element or tube in which a gear is mounted, in mesh with both racks.</p> |
