Abstract
A piston assembly for use in a gas spring or damper can include a piston rod partially positioned within a pressure tube, and a linear position sensing apparatus capable of tracking and determining the velocity of the piston rod. The linear position sensing apparatus can include a sensor, such as a waveguide sensor, connected to the piston rod such that the sensor moves with the piston rod. A beacon, such as a magnet, can be contained within the pressure tube and the sensor can detect the position of the beacon relative to the sensor.
