The component is deformed due to various thermal influences during processing, which compromises the original machining accuracy and introduces errors. In precision finishing, the effect of thermal deformation is particularly significant, leading to processing errors that can exceed 40%. This document describes a temperature measurement system for shaft-type components that enhances accuracy. The system is designed to control the core in a simple and reliable manner, utilizing a high-precision one-chip computer, the 80C552. It can simultaneously calculate the thermal deformation at different temperatures of lower axes. The sensor is embedded between two layers of polyimide foil, incorporating a platinum wire coil with a diameter of 30 microns, and connects to the external environment through two leads. Its thickness is 0.3 mm, making it suitable for curved temperature measurements with minimal heat loss and a relatively large measurement area, ensuring a fast response time. During operation, the sensor can be adhered to an arcual magnet, allowing for convenient and rapid temperature measurement by attaching the magnet to the axle. The signal from the temperature sensor is directed to an amplifier, which employs the AD521 integrated measurement amplifier. This amplifier features high input impedance, low offset current, and a high common-mode rejection ratio. Its gain-to-noise temperature ratio can be adjusted within a range of 0.1 to 1000 without the need for delicate resistance connections, as various gain-to-noise temperature ratio parameters have been internally compensated. It effectively mitigates common-mode interference and noise from the mains frequency, static, and electromagnetic coupling.

The temperature measurement system described is crucial for maintaining the precision of shaft-type components during manufacturing processes. The integration of the 80C552 microcontroller allows for real-time calculations of thermal deformation, which is essential for compensating machining errors caused by temperature fluctuations. The sensor's design, utilizing a platinum wire coil, ensures high sensitivity and rapid response, which are critical for dynamic applications where temperature changes may occur rapidly.

The AD521 amplifier enhances the system's performance by providing high input impedance, which minimizes loading effects on the sensor output. The low offset current characteristic ensures accurate signal amplification, while the high common-mode rejection ratio effectively reduces noise interference from external sources. This feature is particularly beneficial in industrial environments where electromagnetic interference is prevalent.

The ability to adjust the gain-to-noise ratio without complex external components simplifies the design and enhances reliability. Internal compensation for various parameters further streamlines the calibration process, allowing for quick adjustments to suit different operational conditions.
