Abstract
A micro-position gap sensor assembly, including a structural housing, a flexible diaphragm fixedly attached at a first end of the structural housing, and a shaft orthogonally attached to the flexible diaphragm. The micro-position gap sensor assembly may further include a first retainer coupled to the shaft, a second retainer formed as a step of the structural housing, and a plate gap sensor. The plate gap sensor may include a non-contact sensor plate biased by a compression spring so that the non-contact sensor plate is held against a portion of the second retainer. The plate gap sensor may further include a target plate positioned adjacent the non-contact sensor plate and separated therefrom by a gap. The target plate may be biased by a return spring so that the target plate is held against a portion of the first retainer. The target plate may be coupled to the shaft.
