自动记录式通风干湿温度装置

Automatically-recording type ventilating dry humidity device

Abstract

一种自动记录式通风干湿温度装置,包含有保湿装置、风道(16)、隔板(14)、风扇(17)、热电偶湿球(9)、热电偶温差湿球(10)、热电偶温差干球(11)、热电偶干球(12)、保湿纱布(7)、数字采集记录处理器(24)和恒温器(23);风道管(16)的测量端口被隔板(14)设置为分离成测量腔I(13)和测量腔II(15),热电偶湿球(9)和热电偶温差湿球(10)设置在风道管(16)的测量腔I(13)中,热电偶温差干球(11)和热电偶干球(12)设置在风道管(16)的测量腔II(15)中,热电偶温差湿球(10)和热电偶温差干球(11)的铜电极输出端、热电偶湿球(9)和热电偶干球(12)的铜和康铜电极两输出端设置为与数字采集记录处理器(24)的入口端连接。因此不容易丢失极限值,能及时记录保存微变动状态过程的数值。
The invention relates to an automatically-recording type ventilating dry humidity device which comprises a moisturizing device, an air flue (16), a partition plate (14), a fan (17), a thermocouple wetbulb (9), a thermocouple temperature difference wet bulb (10), a thermocouple temperature difference dry bulb (11), a thermocouple dry bulb (12), moisturizing gauze (7), a digital collecting and recording processor (24) and a thermostat (23), wherein a measuring port of the air flue pipe (16) is divided into a measuring cavity I (13) and a measuring cavity II (15) by the partition plate (14); thethermocouple wet bulb (9) and the thermocouple temperature difference wet bulb (10) are arranged in the measuring cavity I (13) of the air flue pipe (16); the thermocouple temperature difference drybulb (11) and the thermocouple dry bulb (12) are arranged in the measuring cavity II (15) of the air flue pipe (16); and the copper electrode output ends of the thermocouple temperature difference wetbulb (10) and the thermocouple temperature difference dry bulb (11), and the copper electrode output ends and the constantan electrode output ends of the thermocouple wet bulb (9) and the thermocouple dry bulb (12) are connected with the inlet end of the digital collecting and recording processor (24), thereby being difficult to lose a limit value and recording and storing a numerical value in the micro-change state process in time.
