Sensor calibration

This article investigates the physicochemical properties of the high-entropy alloy MoNbTaVW and its potential application in strain gauge sensors for structural health monitoring of composite constructions, particularly wind turbines. The material’s suitability for accurate mechanical tension measurements is analyzed, taking into account its high thermal stability, resistance to corrosion, and tolerance to radiation exposure. It is demonstrated that MoNbTaVW maintains structural integrity at elevated temperatures, outperforming conventional metals commonly used in sensing systems.

The accuracy characteristics of the ultrasonic range finder are studied in the work. The latter has been calibrated by a laser interferometer. The problems that arise are described. The calibration method was implemented with the help of a measuring installation, along the rail of which an ultrasonic sensor - range finder and a laser interferometer were fixed.
