This work characterizes a force-balanced piston gauge (FPG), model FPG8601, as a primary pressure standard over its whole operation range from 1 Pa to 15 kPa. To date, FPGs have been handled as secondary standards that are usually calibrated against

Precise evaluation of form error is important for quality control in the manufacture of camshafts. For circular arc cams, a conventional method is to fit each arc segment of the cam individually. In such a case, at the connecting points of two fitted

A concept for a novel diameter and form measuring instrument is described. The concept utilizes two independent z-axes towers on a common x-axis which each carry their own y-axis and tactile probes. The X- and Z-axes are equipped with metrology frame

Within an international project directed to the new definition of the base unit kelvin, the Boltzmann constant k has been determined by dielectric-constant gas thermometry at PTB. In the pressure range from about 1 MPa to 7 MPa, 11 helium isotherms h
