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.
