ABSTRACT:
A method and apparatus for measuring a pressure, particularly the pressure of a fluid, employ a pressure-charged measuring piston movable in a cylinder and connected to a load or displacement measuring device. The piston is maintained floating or contact-free within the cylinder by hydrostatic or pneumatic fluid in the form of a release agent supplied between the piston and the cylinder under pressure.
