This gradient is the difference between the material's initial moisture content and the moisture content (dew-point
) of the dry air.
As the encompassing air gets dried, the dew-point
is brought down and the temperature that is maintained on the cool evaporator loop likewise is lowered.
On this plot, temperature glide is the horizontal distance (meaning at fixed pressure) between the bubble point and dew-point
lines of the zeotropic blends.
Their range of dew-point
hygrometers are used for a variety of compressed air applications around the world, including compressed air systems, desiccant and rotary wheel dryers, fluid beds, refrigerant membranes and silica gel.The current product range includes dew-point
transmitters, chilled mirror hygrometers and portable instruments as well as humidity calibration equipment.
high-speed portable dew-point
hygrometer, which features a custom-designed sampling kit, is capable of making reliable measurements in natural gas streams at up to 350 bar, giving readings that are representative of actual process conditions.
These climatic conditions include dry-bulb, dew-point
and wet-bulb temperatures at various frequencies of occurrence, as well as other quantities such as average temperatures and precipitation, heating and cooling degree days, wind conditions, clear sky solar radiation, and others.
* Dryers with automatic desiccant regeneration controlled by dew-point
sensors or by material moisture content are best, as overloading the desiccant will reduce process efficiency.
It doesn't fall, but rather forms on an exposed surface when that surface becomes colder than the dew-point
temperature, which depends on the humidity.
MICHELL Instruments has introduced a new S8000 RS high-precision dew-point
hygrometer that enables furnace operators to achieve high standards of finishes and quality of metal products at lower annealing temperatures.
MICHELL Instruments is featuring the latest development of its hydrocarbon and water dew-point
analyser, the Condumax II, at Adipec 2012.
KMP is purchasing 290 amine-treating and dew-point
control plants predominantly located in Texas and Louisiana, with additional facilities in Mississippi, Oklahoma, Arkansas and Kansas.
Michell Instruments' MDM300 advanced dew-point
hygrometer can save engineers weeks of waiting time each year.
