用微處理器的隨線式微波測濕系統(tǒng)
A MICROWAVE SYSTEM FOR MEASURING HUMIDITY OF CLASTIC DIELECTRIC ON CONVEYER WITH PROGRAMMABLE COUNTER
-
摘要: 本文介紹一種隨線式微波測濕系統(tǒng)。本系統(tǒng)所用傳感器靈敏度較高,線性較好,適合于在傳送帶上測量碎屑伏電介質(zhì)的含水量。由于采用了可編程計算器采集和處理數(shù)據(jù),提高了測量準(zhǔn)確度。本系統(tǒng)已在上海焦化廠精煤傳送帶上做了動態(tài)實(shí)驗(yàn),所得結(jié)果與實(shí)際含水量基本相符。

Abstract: A sensitive linear sensor, which is suitable for ineasuring humidity of elastic dielectric on conveyer, is presented. A programmable counter is used to improve the measuring accuracy. The dynamic test of this system has been completed on the conveyer in Shanghai Coking Factory. The experimental results are in good agreement with the actual humidity of the coking coal. -
