WebPsychrometers. All psychrometers derive an environment’s wet-bulb and dew point temperatures from a precise measurement of relative humidity. The original psychrometer had two thermometers mounted together with a handle attached on a chain. One thermometer was ordinary. WebDesign of Psychrometer. We can say it is a simple hygrometer – which is a device measuring humidity. It has two bulbs both connected with a thermometer. One bulb is wet while the other is dry. We expose the dry bulb to the air so as to measure the temperature. We cover the wet-bulb with a cloth wick and dip it in water until it is ready to use.

WebThe psychrometer is used to make spot readings, to take readings in areas where there are no hygrothermographs or other monitoring devices, and to calibrate hygrothermographs and hygrom- eters. (See Conserve 0 Gram 312.) There are two types of psychrometers: the sling psychrometer and the aspirating psychrometer. Although the principles of psychrometry apply to any physical system consisting of gas-vapor mixtures, the most common system of interest is the mixture of water vapor and air, because of its application in heating, ventilation, and air-conditioning and meteorology.

WebApr 25, 2012 · Assmann psychrometer. A special form of the aspiration psychrometer, developed by Assmann. Two mercury thermometers, mounted vertically side by side in a chromium- or nickel-plated polished metal frame, are connected by ducts to an aspirator. Each thermometer is located inside a pair of coaxial metal tubes, highly polished inside … WebA sling psychrometer can be used to find relative humidity, which is expressed as a percentage. It is computed by multiplying the amount of moisture in the air at a given temperature, dividing by the maxi-mum amount of moisture the air could contain at that same temperature, and then multiplying the quotient by 100.
