Background. Currently, there is a constantly growing need for advanced measuring and control tools, including displacement sensors with high accuracy and speed, the ability to operate in difficult environmental conditions (large temperature differences, aggressive environments, mechanical loads, high humidity, high pressures, etc.). The aim of the study is to develop a contactless vibration displacement measurement system based on an eddy current sensor. Materials and methods. In solving the tasks, full-scale testing methods were used. Results. The operability of the developed system was tested and calibration characteristics were taken at high and low supply voltages, with different anchor materials. The operability of the system under conditions of exposure to high and low ambient temperatures was also confirmed.
