A6b: New Real-Time Position Measuring System for Hydraulic Piston Accumulators on HPUs
Now a new approach has been developed using a laser through a specific high-pressure glass.
The laser is able to measure the position of the piston, in real time, without having a cable that could damage the piston seals or the wall of the accumulator. Using the signal from the laser sensor, an adapted digital display or a vertical bar graph would be able to show the real time, relative position of the piston inside the accumulator, to the maintenance crew.
