A world renowned manufacturer of plant machinery contacted Gill for a remote solution to measuring brake pad wear on large rigid dump trucks.
A customised solution was required which would eliminate the costly downtime of removing the wheels and could withstand the pressure of the hydraulic brake circuit internally.
The sensor had to be designed to withstand the pressure of the brake circuit hydraulic fluid without leakage. Built into the axle assembly, the sensor was not accessible once the wheels had been fitted, so robustness and reliability were paramount.
A novel solution was developed to measure the position of the metallic detector rod attached to the brake pad, through a one-piece, pressure resistant metal housing, which also incorporated the mounting interface.
