A humidistat or hygrostat is an electronic device analogous to a thermostat but which responds to relative humidity, not temperature. A typical humidistat is usually included with portable humidifiers or dehumidifiers. It can also be included with combined air cleaner or humidifier units to control a home's humidity level or any other indoor space.
v. t. e. A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much water vapor it contains. [1] Humidity measurement instruments usually rely on measurements of some other quantities such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed.
Hygrometer. Dry / Wet-bulb temperature. v. t. e. Psychrometrics (or psychrometry, from Greek ψυχρόν (psuchron) 'cold' and μέτρον (metron) 'means of measurement'; [1][2] also called hygrometry) is the field of engineering concerned with the physical and thermodynamic properties of gas - vapor mixtures.
Humidity indicates the likelihood for precipitation, dew, or fogto be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point.
A humistor has a ceramic composition comprising at least one component having a spinel type cubic symmetry selected from the group consisting chromates, stannic or titan oxides of different metals like MgCr 2 O 4, FeCr 2 O 4, NiCr 2 O 4, CoCr 2 O 4, MnCr 2 O 4, CuCr 2 O 4, Mg 2 TiO 4, Zn 2 TiO 4, Mg 2 SnO 4 and Zn 2 SnO 4, and, if desired, at least one component selected from the group ...
A dehumidifier is an air conditioning device which reduces and maintains the level of humidity in the air. [ 1 ] This is done usually for health or thermal comfort reasons or to eliminate musty odor and to prevent the growth of mildew by extracting water from the air. It can be used for household, commercial, or industrial applications.
A thermostat can often be the main control unit for a heating or cooling system, in applications ranging from ambient air control to automotive coolant control. Thermostats are used in any device or system that heats or cools to a setpoint temperature. Examples include building heating, central heating, and air conditioners, kitchen equipment ...
An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country, or engineering ...
