<p>A method for calibrating pneumatic actuators comprising a containment structure (2) in which a diaphragm (4) is mounted which delimits a variable-volume chamber (5) whose internal pressure may be varied, and a rigid rod (8) able to slide through the containment structure (2) and connected to the diaphragm (4). At least one connecting head (11) can be mounted on an external second end (10) of the rigid rod (8) for connecting to an element to be controlled, such as a crank of a turbo-compressor. The method comprises the operating steps of varying the pressure in the variable-volume chamber (5) until a predetermined value is reached, thus bringing the rigid rod (8) to a corresponding operating position, positioning the connecting head (11) in a predetermined position relative to the containment structure (2) of the actuator and constraining the connecting head (11) to the rigid rod (8) in such a way that with the rigid rod (8) in the operating position the head (11) is in the predetermined position relative to the containment structure (2).</p> |
