|Title:||A novel concept in the design of a psychrometer|
|Authors:||Sen, Sunit Kumar|
|Abstract:||A novel psychrometric method for measurement of humidity of a process is proposed. The design of a psychrometer is a complex one due to simultaneous introduction of two variables at the same time, viz., the meter current is dependent on both the relative humidity and ambient temperature. The circuit design has been so made that the said current would depend only on the relative humidity of air and independent of temperature variations at the place of measurement. Theoretical calculations show that the maximum error in the measurement of the meter current would be limited to within +1.6% at 120°F and -2% at 60°F for 100% relative humidity while the same would be within ±1.75% for the entire temperature range 60°-120°F for 0% relative humidity.|
