    Abstract: Measurement sensor for length or distance changes, particularly for non-contacting measurement of torques of rotating shafts. In known measurement sensors, the length or distance change (.DELTA.x) is amplified by a mechanical lever system and is then converted into an electrical quantity. In the novel measurement sensor of the present invention, the length or distance change (.DELTA.x) to be measured is transmitted to a displacer in order to enhance the precision. A displaced liquid, particularly mercury, is introduced into a capillary and the length of a liquid column in the capillary is converted into an electrical quantity, preferably as a change of a resistor. The new measurement sensor is particularly suitable for torque measurement.

    Abstract: A device for transducing a force into a pneumatic signal comprises an air obstructing body composed of a rigid ball and supporting disc against which a force to be transduced is applied, and an air nozzle including an opening facing the rigid ball, the air nozzle being connected to a compressed air supply unit. Compressed air from the opening of the air nozzle flows away along the surface of the rigid ball. As a result the above, the air obstructing body moves upward or downward by the difference between a compressed air force acting upon the rigid ball compressed and the applied force to be transduced. When both forces balance, the air obstructing body settles in an equilibrium position and at that time, back air pressure of the nozzle has a relationship which is proportional to the applied force to be transduced. Back air pressure is measured by an air pressure measuring instrument connected to the air nozzle as a pneumatic signal.

    Abstract: A weighing valve mounted on a vehicle to produce a fluid having a pressure proportional to the load of the vehicle is activated by a force translating device which produces a proportionate force to the valve to thereby generate fluid flow changes of pressure signalling the loading on the vehicle. The force translating device has a differential piston with a plunger of smaller diameter for actuating the valve communicating with a plunger of larger diameter responsive to the load. The plunger and piston are interconnected through a deformable, incompressible medium such as silicone rubber into which both the end and sides of the smaller diameter plunger are extended thereby dampening vibrations.
