Description
Technical field
The utility model relates to a kind of physical measurement techniques field, particularly relates to a kind of hygrometer.
Background technology
The analyzer for physical property of measurement gas humidity.Humidity represents the vapour content in gas, has absolute humidity and relative humidity two kinds of method for expressing.Absolute humidity refers to the absolute content of water vapour in gas, and the most frequently used unit is gram of/meter of ^3.When uniform temperature, pressure, the vapour content in unit volume has certain limit, is called saturated vapor content.The ratio of saturated vapour content in same volume gas when relative humidity refers to the absolute content of water vapour in gas and same temperature, pressure, conventional sign is %R.H..Hygroscopicly to have many uses, such as, in the production runes such as superpure metal smelting, textile processing, papermaking and printing and dyeing and food storing and meteorologic survey etc., often need the humidity measuring or control air or industrial flow gas with hygrometer.The principle of complete relative humidity measured by hygrometer: because the bulb, of wet-bulb thermometer encloses cotton yarn, the lower end of cotton yarn is soaked in water, evaporation of water and make wet-bulb thermometer temperature registration always lower than dry-bubble temperature meter temperature registration (temperature) this temperature gap with water evaporation speed (namely relative humidity) at that time about. according to the reading of two temperatures meter, the relative humidity of air can be found from table or curve.
That common psychrometer is in close position by two, identical glass-stem thermometer forms, and is wherein surrounded by a nylon net outside the thermometer bulb of, and the other end of net is soaked in water.Due to capillarity, the net around thermometer bulb remains moisture state.During the evaporation of net surface moisture, heat absorption then makes net temperature reduce.So, the temperature indicated by this thermometer (being called wet bulb thermometer), just than another not bag net thermometer (being called dry bulb thermometer) indicated by temperature low.The relative humidity of ambient gas is lower, and the speed of net transpiring moisture is faster, and thus the amplitude of temperature reduction is larger.According to this temperature difference and dry-bulb temperature, the relative humidity of ambient gas can be found from the table of comparisons appended by instrument.This hygrometer structure is simple, is mainly used in meteorologic survey and indoor air humidity measurement.
Current existing hygrometer complex structure, inconvenient operation, has easily produced measuring error larger during use.
