Height sensor and air spring apparatus incorporating the same in the air chamber

摘要: An air spring apparatus with an internal height sensor is provided. The includes end cap member, a piston member and flexible annular sleeve connected therebetween forming sealed chamber. sensing element indicating mounted within the to one of member. has first portion second elastic therebetween. length defines level sensible by such that movement relative produces much smaller proportional element. This proportion reduction allows measure relatively large change in height.
