Temperature Distribution Measurement

Temperature distribution is an important process parameter of steel plates during electromagnetic induction heating treatment. This study uses the digital image correlation method to develop an effective non-contact temperature measurement that allows obtaining valuable information about the temperature value of a high temperature steel plate specimen and analyzing its temperature distribution. A principle of thermal radiation temperature measurement based on the color chagre couled device (CCD) technology was introduced. The image processing system encapsulates the image update module, form mode module, image event module and temperature analysis module. The error analysis and temperature calibration were carried out to make sure the error deviation of the measurement system was within a small range. The temperature distribution of B1500HS at high temperature was analyzed by the designed measurement system which was in good agreement with the result from Raynger 3i Plus temperature gun, indicating that the measurement system based on image processing basically meets the requirements of temperature distribution measurement of a high temperature steel plate, and provides an important reference for a high temperature steel plate in non-contact temperature distribution measurement.

Ceramic pole attenuator is an important part in TWT. The performance of TWT is closely related to the attenuation distribution of ceramic pole. The measurement of attenuation distribution was a difficult problem all the time. The traditional measurement method characterize the attenuation distribution by measuring the resistance distribution. The main disadvantage of this method is that result can not characterize ceramic pole’s performance in microwave condition. In this paper we select double-ridge waveguide as measurement transmission line, and based on the classical “Transmission and Reflection Method” an attenuation distribution measurement system was developed. This measurement system provides a convenient method to get accurate attenuation distribution in microwave condition. X-band and Ku-band ceramic pole attenuators were measured, and curves of attenuation distribution were given in this paper.
