Abstract
A brake wear monitoring system for measuring extended wear lengths includes a processing unit, a plurality of linear Hall sensors in electronic communication with the processing unit, a wear pin coupled to a brake stack, the wear pin comprising a magnetic portion, wherein the plurality of linear Hall sensors are configured to detect a position of the wear pin via the magnetic portion, and the processing unit is configured to generate an output signal, based upon the position of the wear pin relative to the plurality of linear Hall sensors, to indicate a wear status of the brake stack.

A brake wear monitoring system, comprising:
- a processing unit;
- a plurality of linear Hall sensors in electronic communication with the processing unit;
- a wear pin coupled to a brake stack, the wear pin comprising a magnetic portion;
- wherein the plurality of linear Hall sensors are configured to detect a position of the wear pin relative to the plurality of linear Hall sensors via the magnetic portion, and
- the processing unit is configured to generate an output signal, based upon the position of the wear pin relative to the plurality of linear Hall sensors, to indicate a wear status of the brake stack.
A braking arrangement, comprising:
- a brake stack;
- a processing unit;
- a plurality of linear Hall sensors in electronic communication with the processing unit;
- a wear pin coupled to the brake stack, the wear pin comprising a magnetic portion;
- wherein the plurality of linear Hall sensors are configured to detect a position of the wear pin relative to the plurality of linear Hall sensors via the magnetic portion, and
- the processing unit is configured to generate an output signal, based upon the position of the wear pin relative to the plurality of linear Hall sensors, to indicate a wear status of the brake stack.
A method for brake wear monitoring, comprising:
- receiving, by a controller, a feedback signal from a plurality of linear Hall sensors, wherein the plurality of linear Hall sensors are disposed along a line of action of a wear pin;
- calculating, by the controller, a position of the wear pin, wherein the plurality of linear Hall sensors detect the position of the wear pin via a magnetic portion of the wear pin;
- and
- sending, by the controller, a wear status signal to indicate a wear status of a brake stack.
