Abstract
The subject invention reveals a distance measuring device comprising: a sensing module, a target module, and an evaluating module, wherein the sensing module and the target module are mountable so as to execute a movement with respect to each other along a movement trajectory, wherein the target module comprises a magnetic field generating element having a magnetic pole axis, wherein the sensing module comprises a first magnetic field sensing array being arranged distant to the movement trajectory. The sensing module and the target module can advantageously be situated within the pressurizable chamber of an air spring which is defined by (contained within) a first mounting plate, a second mounting plate, and a flexible member of the air spring.
