Measurement of the Surface of Textiles During Microwave Drying Using a Thermographic Phosphor
Source abstract
Abstract
Surface temperature measurements of textile maierials during exposure to microwave energy are nearly impossible to obtain using conventional temperature measurement methods. Wool fabric surface temperatures were obtained using laser-induced fluorescence of the thermographic phosphor, europium-doped lanthanumoxysulfule (La202S :Eu3 ÷). The thermo graphic phosphor temperature technique enables contact-free temperature measurement of thin materials in areas that are difficult to access or are in hazardous environments. Wool temperatures ranged from 60°C to 91°C during a ten minute exposure of microwave energy (2.45 CHz frequency) at nine power settings.
