Condition Monitoring Without New Gadgets
You do not need a fleet of sensors to read a machine’s whispers. Start by using senses skillfully and borrowing simple tools already in the shop—infrared thermometers, handheld tachometers, stethoscopes, feeler gauges, or a basic vibration pen. Combine these with historian trends from PLC or SCADA data to flag drift earlier. The key is consistency: collect, compare, and react. Small, regular samples create a storyline, turning ambiguous hunches into confident calls that avert lengthy, avoidable stoppages.
