Explanation: Pneumatic actuators at the ends of the beam centre it laterally and clamp it. Servo-motor driven clamps secure the beam at four points with a pre-determined clamping force. Haversine loading is applied to the beam via the built-in digital servo-controlled pneumatic actuator. The innovative “floating” on-specimen transducer measures and controls the *** true beam deflection *** irrespective of loading frame compliance.
