“…It is important to note, however, that the above temperature compensation methods only consider temperature compensation for a single sensor, and not multi-sensor compensation. Previously, the compensation applied to pressure scanners usually used multiple regression fitting method, which is primarily represented by the least squares method and fourthorder fitting method [20,21], and the traditional compensation algorithm face the problem of low compensation accuracy because of more calibration data points and increased calculation, which is no longer applicable to the current wide temperature range of multi-channel pressure scanning valve temperature compensation. A thermal compensation method for multiple temperature sensors in machine tools has been proposed in an earlier study [22].…”

“…An algorithm based on a multipoint temperature measurement system is proposed in a previous investigation [23] for ring laser gyroscope bias compensation, which improves the model's accuracy and generalization. A four-channel high-precision pressure test system was designed [21] using curve fitting studies to achieve highprecision pressure monitoring in real time in the range of 24 • C-400 • C. A researcher [24] describes a method for integrating low-cost, uncalibrated thermal sensors into a software feedback loop for real-time gain and thermal compensation of embedded sensor arrays. Another study [25] proposed a simple and generic structural health monitoring and measurement system that compensates for temperature effects.…”

To solve the problem of the measured value of pressure scanners drifting nonlinearly with temperature change when measuring pressure, resulting in low accuracy, this paper proposes and develops a new calibration system based on neural networks for pressure scanners. Specifically, we start by calibrating the pressure scanner production process, then design the sealing device applicable to the working environment of pressure scanner, and finally install the calibration system of pressure scanner for calibration experiments, so that accurate measurement results can be obtained. In addition, at the algorithmic level, this paper proposes a whale optimization algorithm based back propagation (BP) neural network method instead of the traditional least squares method to complete the temperature compensation. Both the off-line compensation results and the compensated on-line experimental results show the high measurement accuracy of this temperature compensation method. The full-scale error (FS) is 0.07%, the coefficient of determination (R2) =99.27%, with similar results for all channels of the pressure sensor in the temperature environment -40°C to 60°C and absolute pressures ranging from 0 to 1.1Mpa. The result is not only a significant reduction in full-scale error of 0.25%, R2 =91.32% based on conventional algorithm compensation, but also applies to the pressure scanner with wide temperature region, wide range and high accuracy temperature compensation, which is important for its future research of low-cost overall calibration and high accuracy algorithms.

The main objective of this study is to enhance heat transfer for the reduction of temperature in MEMS‐based piezoresistive high‐temperature pressure sensors. The main parameter that affects the sensor performance especially for Aerospace applications is higher operating temperature because there are many electronic components and devices that may fail due to higher temperatures. Prevention of overheating of the electronic components in the sensor is a challenge; hence, the study of heat transfer from hydraulic fluid is of utmost importance. Different types of fin surfaces to enhance the heat transfer rate are studied using ANSYS CFD (computational fluid dynamics). CFD simulations and experiments are carried out to design novel high operating temperature pressure sensors for aerospace applications. This in turn improves performance due to internal thermo‐piezoresistive amplification. In this paper, high‐temperature pressure sensors are designed by CFD analyses and experimentally analyzed for a better understanding of the distribution of temperature in the pressure sensor and thermal variation in the sensor and observe the changes during analysis. Extended fin surface concepts are introduced for better heat transfer and to reduce the fluid temperature inside the sensor that is transferred to the electronic components. ANSYS CFD analysis is carried out to determine the temperature distribution and two models are identified for experimental validation.
