slitasjesensors

Slitasjesensors, or wear sensors, are devices designed to monitor the progressive deterioration of mechanical components due to friction and wear. They provide information on remaining life or rate of wear to support maintenance planning and prevent unexpected failures. The term is used across industries and can describe passive indicators or active sensor systems embedded in components.

Common sensing approaches include inductive or capacitive thickness measurement, ultrasonic thickness gauging, optical surface monitoring, magnetic field sensing, acoustic emission, vibration analysis, temperature and lubricant condition sensing, and MEMS-based micro-sensors. Some sensors are contact-based, measuring material loss directly; others infer wear from changes in friction, damping, or lubricant properties.

Applications span automotive, industrial machinery, aerospace, energy, and manufacturing. In automotive, brake pad wear sensors detect pad thickness or friction state, signaling replacement. In machinery, bearing, gear, or seal wear sensors monitor clearances and surface condition. In aerospace and energy, wear sensors are used on turbine blades, gearboxes, and pumps to support predictive maintenance.

Data from slitasjesensors can be integrated into condition monitoring systems and IoT platforms to enable predictive maintenance, remote diagnostics, and optimized spares management. Benefits include reduced downtime, lower maintenance costs, extended component life, and improved safety. Some wear sensing methods also monitor lubricant quality and contamination, offering early warning of lubrication-related wear.

Challenges include sensor durability in harsh environments, calibration, false positives, and integration costs. Ongoing research focuses on more robust MEMS, wireless power and communication, and multi-parameter sensing that combines wear, temperature, and lubrication data for more accurate remaining-life estimates.
