“…that meet modern requirements when working in extreme operating conditions with increased dust, humidity, significant temperature differences, etc. [1,2,3]. A comparative analysis of the main characteristics of existing motion sensors shows that the most promising direction in solving the actual problem of more efficient use of monitoring and control systems is the use of biparametric resonant motion sensors (BRMS), which, by their properties (high reliability and stability of characteristics in extreme operating conditions, and also high output power) best meet the modern requirements of monitoring and control systems.…”
