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.
The traditional Stevenson screen is a box shape, constructed of wood, in a double-louvered design.[6] However, it is possible to construct a screen using other materials and shapes, such as a pyramid. The World Meteorological Organization(WMO) agreed standard for the height of the thermometers is between 1.25 and 2 m (4 ft 1 in and 6 ft 7 in ...
Thermo-hygrograph. A thermo-hygrograph or hygrothermograph is a chart recorder that measures and records both temperature and humidity (or dew point). Similar devices that record only one parameter are a thermograph for temperature and hygrograph for humidity. Thermographs where the variations are recorded using photography were described by ...
Humidity measurement is one of the more challenging technical problems in basic physics, mainly because small microclimate variations from place to place make it nearly impossible to maintain a consistent RH throughout the environmental chamber used for calibrating the devices. Two thermometers can be compared by immersing them in an insulated ...
A bimetallic coil from a thermostat reacts to the heat from a lighter, by uncoiling and then coiling back up when the lighter is removed. A bimetallic strip or bimetal strip is a strip that consists of two strips of different metals which expand at different rates as they are heated. They are used to convert a temperature change into mechanical ...
Component of Stirling radioisotope generator is heated by induction during testing. Induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an inductor that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold ...
Freeze stat. Air coil freeze stat. A freeze stat is a temperature sensing device for HVAC that monitors a heat exchanger to prevent its coils from freezing. Freeze stats can be used on both refrigerant -to- air, and refrigerant -to- liquid type heat exchangers and serve different purposes with similar goals for each.
Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a heat-resistant ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum (Pt), nickel (Ni), or copper (Cu).
