Abstract
A sensing assembly. The sensing assembly is spaced apart from a magnet that has a magnet length, and includes a compensation module and a string of magnetic sensors that has a string length. The magnetic sensors are grouped into a plurality of magnetic sensor groups. Each of the magnetic sensors generates a respective intermediate signal based on the magnet. The compensation module assigns a plurality of respective gains to the respective magnetic sensor groups based on a difference between the magnet length and the string length, and applies the respective gains to the respective intermediate signals of the respective magnetic sensor groups to generate respective adjusted signals.
