Abstract
Abstract
Platinum film thermistor is developed by combining platinum film thermistor with thin film technology, which solves the cost and application problems of platinum film thermistor components. The principle, fabrication process and application of platinum film thermistor are introduced. A temperature acquisition device of platinum film thermistor is designed. It is verified that the platinum film thermistor has the characteristics of fast response and high accuracy. The temperature data of aluminum alloy plate heated at a single point is collected by using the temperature measurement system. The characteristics of the platinum film thermistor model are verified by comparing the collected data with the simulation data. The results show that the platinum film thermistor can accurately and efficiently complete the fine temperature change measurement, which has a broad development prospect.
