厂家所生产的毛纤维质量,在很大程度上与污毛的质量数据,比如湿度有关。最近,苏联库泰依斯市仪表设计局研制成功一种型污毛包湿度检测仪,用于毛纤维初加工企业进货时检验包装在包内的污毛湿度,以便确定它贮存时间的长短和供给加工的先后次序.根据该仪器对周围湿度和气温影响的稳定性,它可在环境温度为5～40℃之间的温带和寒带的广大地区内使用. 图1表示的是型湿度仪工作原理的框图。湿度仪采用了F-计电路。来自测试振荡器1的信号,聚集到场效应管上,其频率随着初级测试变频器的电容而变化,然后信号输入到对比单元2。标准振荡器3
The quality of the woolen fibers produced by the manufacturer is to a large extent related to the quality of the soiled material, such as humidity. Recently, the Soviet Union Kutaisi Instrument Design Bureau successfully developed a type of dirt bag moisture detector for wool fiber processing enterprises to purchase the first inspection package in the bag of soil moisture, in order to determine the length of its storage time and According to the instrument on the surrounding humidity and temperature stability, it can be used in a wide area of the temperate and boreal zone between the ambient temperature of 5 ~ 40 ° C. Figure 1 shows the operation of the type of hygrometer Block diagram of the principle. Humidity meter with F-meter circuit. The signal from Test Oscillator 1 is collected on the Field Effect Transistor and its frequency varies with the capacitance of the primary test drive. The signal is then input to Compare Unit 2.
