Correction of the Temperature Component of Error of Piezoelectric Acceleration Sensor

Abstract

In the aviation and aerospace industries, systems of artificial intelligence are being intensively implemented. For their effective functioning, it is necessary to provide reliable primary information. Information is collected by primary converters. In various systems of aviation technology, piezoelectric accelerometers are widely used as primary transducers. In particular, they are part of inertial navigation systems. These systems do not need external sources of information and are not affected by external interference. Therefore, they are widely used in aircraft for various purposes. These accelerometers are also used in other aircraft systems. In systems for monitoring the operation of gas turbine engines, systems for registering overloads. However, in conditions of high-temperature differences, shocks, vibrations, and significant accelerations, piezoelectric transducers have inherent flaws that affect the linearity and accuracy in measuring these values. Especially piezoelectric transducers are critical to extreme temperatures.
