Abstract

Ultracentrifuge rotor needs high-speed operation in a vacuum environment

the traditional contact type temperature measurement produces large errors.Based on the principle of infrared temperature measurement

using infrared thermopile temperature sensor to direct measure the rotor temperature.The overall design and measurement circuit’s hardware design are described.Impact of environmental temperature and rotor material emissivity on measurement precision is focused on

and a corresponding compensation algorithm is used to improve the precision.The simulation experiments and practical tests show that the system can meet the temperature control requirements of ultracentrifuge.
