Abstract
A low-mass pointer element for a pressure measuring mechanism is made from a lightweight plastic paper material and includes a center hub having a through aperture which is sized to accommodate a rotatable shaft end of the pressure measuring mechanism. An indicating end of the pointer element is sloped downwardly toward a dial face relative to the center hub to prevent parallax along with a counterbalancing portion. The indicating end is inwardly tapered to a flattened distal end to provide equivalent stiffness, but with considerably less mass so as to significantly reduce stress loads on a corresponding movement mechanism.
