Claim 6:
7. A system comprising:
a piston-cylinder arrangement including a piston that is movable within a cylinder and a rod coupled to the piston and extending through the cylinder, wherein the piston divides an internal space of the cylinder into a first chamber and a second chamber;
a rod-side head piston seal positioned on the piston to form a seal between the piston and the cylinder to preclude leakage between the first chamber and the second chamber;
a rear head piston seal positioned on the piston and axially-spaced from the rod-side head piston seal along a length of the piston;
a first pressure sensor configured to measure pressure level in the first chamber during movement of the piston to generate a first pressure versus time curve;
a second pressure sensor configured to measure pressure level in the second chamber during the movement of the piston to generate a second pressure versus time curve; and
a controller performing operations comprising:
comparing the first pressure versus time curve and the second pressure versus time curve to a baseline pressure versus time curve,
determining, based on the comparing, whether the rod-side head piston seal or the rear head piston seal has degraded during use of the piston-cylinder arrangement, and
providing an indication of which of the rod-side head piston seal or the rear head piston seal has degraded.
