| Popis: |
An aspirated psychrometer system using thermopiled copper-constantan sensors is described. Field data are presented showing temperature and humidity profiles obtained over a turf crop by nine self-contained units mounted on a 6 m mast. Temperature and humidity can be determined with accuracies of 0.025C and 0.15 mm Hg vapor pressure. The units are relatively inexpensive and easy to fabricate. The wet-bulb element, a porous ceramic cup supplied with a continuous column of water from a reservoir, provides more reliable and less critical operation than the conventional cotton-wick elements. |
