Automatic integrated air humidity measuring device

Abstract

The invention discloses an automatic integrated air humidity measuring device, which comprises an integrated measuring part, a data processing part and an air extraction pipe, wherein the integrated measuring part comprises a main body support frame, an electromagnet, a support round disc, a weighing support frame, a fixing frame, a cantilever beam type mass sensor, a temperature measuring moduleand a moisture absorption module; moisture absorption materials are filled inside the moisture absorption module; the support round disc can rotate around the circumference and is provided with firstplacement holes in array distribution along the circumference; one end of the weighing support frame is fixed at the measuring end of the cantilever beam type mass sensor; the other end of the weighing support frame is provided with second placement holes; the moisture absorption module to be tested is connected with one end of the air extraction pipe through the fixing frame; the data processingpart comprises an air extraction module and an interaction module; the air extraction module is connected with the other end of the air extraction pipe; the integrated measuring part and the data processing part can be arranged in different places or can be assembled into a whole. The moisture absorption module can be automatically replaced; the mass change of the moisture absorption module to betested can be measured on line in real time, so that the automatic maintenance-free measurement is realized.

Description

technical field [0001] The invention belongs to the field of meteorological parameter measurement, and more specifically relates to an automatic integrated air humidity measurement device. Background technique [0002] In the fields of meteorological monitoring, outdoor experimental operation, high humidity area operation, etc., air humidity / water content is an important physical quantity, which is usually expressed by the method of relative humidity RH (Relative Humidity), which refers to the difference between the water vapor pressure in the air and the saturated water vapor at the same temperature pressure percentage. The measurement of relative humidity depends on several environmental factors. At present, common humidity measurement methods at home and abroad include: dynamic method (such as double pressure method, double temperature method, shunt method, etc.), static method (such as saturated salt method, sulfuric acid method), dew point method, wet and dry bulb meth...
