Lesson 1Common Tools and Monitoring Spots: Pressure, Flow, Temperature, Dirt Sensors, and Shake/Noise SensorsThis part describes tools for watching press hydraulics, including pressure, flow, temperature, dirt, shake, and noise. It shows where to put sensors, their ranges, signal types, and how data helps find problems and plan ahead for fixes.
