粮仓电子测温,是确保储粮安全的主要监测手段,而矩阵法布线,又是电子测温在布线上的一项改革,随着矩阵布线的发展,电子测温敏感元件就出现一个适应矩阵布线要求的新课题。我县一九七六年采用电子测温,八○年试行矩阵布线,八三年全县普及,八四年八五年用热敏电阻加二极管作开关普及率达总储稂的95%以上(除流动粮食部分)有效率达99.6%,去年三月起,我们又以热敏电阻加干簧管和单纯二极管代替测温敏感元件的对比试验,结果表明,二极管代替测温敏感元件,在目前矩阵测温敏感元
Granary electronic temperature measurement, is to ensure the safety of the main grain storage monitoring means, and the matrix method wiring, but also the electronic temperature measurement in the wiring of a reform, with the development of matrix wiring, electronic temperature sensing element to adapt to a matrix Wiring requirements of the new topics. In 1976, our county adopted electronic temperature measurement, tried matrix wiring in 1980, and popularized throughout the county in 1993. Over 95% of the total storage capacity of switches was achieved with thermistors and diodes in 1984. (In addition to the flow of food part) effective rate of 99.6%, since last March, we have a thermistor plus dry reed and simple diode instead of temperature-sensitive components of the comparative test, the results show that the diode instead of temperature-sensing components, in the The current matrix temperature sensing element
