Determining magnitude of compressive loading

摘要

An apparatus for determining a magnitude of a compressive load applied to a piston including a compliant film disposed between first and second elements is provided. The apparatus includes a first part movable with the first element in a movement direction along which the magnitude of the compressive load is to be determined, a second part movable with the second element in the movement direction and a sensor to measure a distance between the first and second parts in the movement direction, the measured distance being related to a deformation of the compliant film as the compressive load is applied.

1. An apparatus for determining a magnitude of a compressive load, the apparatus comprising:
a cap affixed to and movable with an upper portion of a piston in a movement direction along which the magnitude of the compressive load is to be determined; a spring disposed in contact with the cap; a pin disposed to extend through the upper portion of the piston and urged by the spring toward a lower portion of the piston, the pin being thereby movable with the lower portion of the piston in the movement direction; and a sensor to measure a distance between the cap and the pin in the movement direction, the measured distance being related to a deformation of a compliant film disposed between the upper and lower portions as the compressive load is applied.
