Sensor stability assurance problems and their relationship with the overall problems of providing system performance quality

Abstract

Research has been carried out in the field of ensuring the stability of transmitters, which are designed to work in extreme conditions. The complexity of the solved problems and the need for a systemic approach, including structural, material science, are noted. Approaches of leading foreign and domestic companies - manufacturers of sensors and measuring systems to issues of metrological reliability of measuring transducers have been analyzed. Ambiguity of interpretation of the term “stability” by various developers and manufacturers of sensors is shown. Most often, the accompanying documentation for sensors, as well as prospectuses and catalogs indicate a qualitative characteristic, and very rarely quantitative parameters. At the same time, international quality standards indicate the need to disclose qualitative indicators and translate them into quantitative data. The concept of ensuring stability of sensors during their life cycle, based on international quality standards and new design and technological solutions, is proposed. On the example of the beam sensitive element of the metal film pressure sensor, a specific effective technique for stabilizing the electrophysical characteristics of the film heterostructure is shown.

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

“…To the greatest extent, the purity of the process and the minimization of internal mechanical stresses are ensured by the development and implementation of the EAS technology and the preparation of the quality of the connected parts [18,19] into a single integral unit (Fig. [7][8][9][10][11].…”

“…5), in which the MEMS module was manufactured at a third-party enterprise, and the SE was assembled and mounted by the authors themselves. The results of ensuring temporal and parametric stability were evaluated using data obtained for microelectronic sensors described in [11].…”

“…As an example of designs of distributed optical pressure and temperature sensors is given in [11] − Fig. 4.…”

Highly Sensitive Multichannel Fano Resonance-Based Plasmonic Sensor for Refractive Index and Temperature Sensing Application

“…The stability and service life of the designed sensor is another important issue and is out of the scope of this work. When the proposed sensor is intended for working in an extreme environment, it requires to consider special technological operations to minimize the deviation of optical properties because of the external factors [65]. 2.…”

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

“…The article [11] describes methods for monitoring and stabilizing the main parameters of various designs and manufacturing technologies of microsensors, including circuitry and design solutions; for various applications. Their studies have shown that they are complex and require unique technological equipment for the implementation and subsequent stabilization of parameters.…”
