Abstract

A permanent magnet inclinometer for industrial machinery is disclosed. The industrial machine includes an assembly movable relative to the industrial machine, the assembly including a first permanent magnet and a second permanent magnet. The annular magnetic sensor array senses a first magnetic flux associated with the first permanent magnet and a second magnetic flux associated with the second permanent magnet. The annular magnetic sensor array includes a first magnetic sensor sensing the first magnetic flux and a second magnetic sensor sensing the second magnetic flux. a controller receiving a first flux signal for the first flux and a second flux signal for a second flux, analyzing the first flux signal to identify a first peak flux, analyzing the second flux signal to identify the second peak flux. Thereafter, the controller determines the inclination of the industrial machine component based on the first peak magnetic flux and the second peak magnetic flux.

Description

technical field [0001] The present invention relates to inclinometers. Background technique [0002] Tilt is typically measured using a microelectromechanical system ("MEMS"). However, MEMS include tiny moving parts that are susceptible to shock and vibration that can adversely affect the MEMS' ability to accurately measure tilt. Contents of the invention [0003] The invention described herein provides a magnetic inclinometer that can be used to determine the inclination of, for example, a bucket handle, boom, or other component of an industrial machine. The inclination of said industrial machine components is used eg by industrial machine related collision avoidance systems, payload determination systems, position detection systems. The inclinometer includes an array of magnets (eg, permanent magnets) mounted or otherwise coupled to the industrial machine component. An annular magnetic sensor array, such as a Hall Effect sensor or other magnetic detector array, is pro...
