Valve Signature Monitoring
A standalone system that tracks the degradation of hydraulic valves over their lifetime so replacements can be planned ahead of failure.

The problem
The customer wanted to know when a hydraulic valve was starting to wear out, before it failed. With that knowledge they could plan downtime and have a spare ready instead of reacting to a breakdown.
What I built
By recording pressure and position over time, each valve gets a signature that is specific to it. Comparing the current signature with older ones shows whether the valve is degrading and by how much. The delivery project’s software could not do this, so I built a completely independent system in Python.
- Signature capture from PLC pressure and position data.
- Trend comparison against historical signatures with clear plots.
- Independent by design, so it can be added to new and existing projects, which turned it into a new product line.
