An on-line thickness measurement system based on TMS32DF2812

In this paper, a new program including design and application of a high-accuracy system is proposed, aiming to improve the condition that waterproofing membrance production line is lack of effective thickness measurement and controlling technology. TMS320F8212 digital signal processor is used as the control chip. Sensor with high resolution and A/D sampling chip AD976 with high accuracy are used as the functional module. This system could collect and process data with high speed and accuracy. The terminal operating system and display interface are also designed to make better improvement for the review of data after processing. Moreover, more convenient settings will be made for relevant parameters.
