| Popis: | This article discusses methods for converting power and thermal parameters for combined pressure and temperature sensors. The paper shows the dependence of the velocity on the pressure change, i.e. the nature of the p(t) dependence. it is Proposed to show a variety of pressure measurement problems that are reduced to three options: measurement of static and slow-changing pressures, measurement of fast-changing pressures, and measurement of pulse pressures. The most stringent metrological requirements for sensors and systems that measure static and slow-changing processes are shown. The technical task is to improve the measuring device. The technical result is an increase in the accuracy of the pressure measurement, taking into account the additional temperature error. This includes well-known devices such as light separators, microlenses, a micropositioner, a collimating lens, a single-mode working fiber with an aluminum coating for temperature measurement, a hinge for collecting lenses, a photodetector, a signal amplifier, a processing unit, and a thermal compensation circuit. |
