Development of the design and technology for manufacturing a combined fiber-optic sensor used for extreme operating conditions

Abstract

The objects of research are the designs and manufacturing technologies of a combined fiber-optic sensor. It is used in extreme operating conditions. The essence of the task is to study the constructive and technological compatibility of optical and micromechanical principles of simultaneous measurement of several heterogeneous physical quantities. In this regard, the chosen modular conversion principle solves the problem of combined conversion. The developed design and technology of the electro-adhesive connection make it possible to significantly reduce the internal mechanical stresses in the sensor and thereby increase the stability of the combined sensors in extreme operating conditions. Analytical models linking the magnitude and orientation of internal mechanical stresses with the characteristics of temporary stability for complex structures, as a rule, are absent. In practice, the obtained research results can be applied to combined pressure and temperature sensors, pressure and vibration, etc.

The use of technologies for stabilizing the electrophysical characteristics of sensor structures used in the development and manufacture of measuring transducers

“…Let's look at these factors in more detail. The vast majority of static-dynamic pressure sensors used in industry use three types of physical conversion principles: piezoresistive, piezoelectric and, to a lesser extent, capacitive [19][20][21][22][23][24][25].…”
