Development of a High-Performance Fluid Infrared Temperature Measurement System

In this paper, a high-performance fluid infrared temperature measurement system without the need for “radiance correction” through an analysis of liquid fluid properties was proposed based on the Blackbody Radiation Theory and Max Planck’s Quantum Theory. In terms of practical application, the system can be calibrated by a high-precision contact-type thermodetector at a time. Then, the resulting data were fitted to complete a continuous curve to meet the measured temperature variation of the liquid fluid. Accordingly, the precise temperature is measured. A higher pertinence of the system makes it easier for a real-time liquid temperature monitoring with accuracy up to 0.1%. This method can also be extended to other non-contact temperature measurement field.
