METHOD OF MEASUREMENT OF HUMIDITY

摘要

FIELD: measuring equipment.SUBSTANCE: on the sensor element on surface acoustic waves and on the reference device on the surface acoustic waves an interrogation signal is set, which is converted in the sensor element on the surface acoustic waves and the reference device on the surface acoustic waves. The amplitude of the signal envelope at the output of sensor element on the surface acoustic waves and the amplitude of the signal envelope at the output of the reference device on the surface acoustic waves is registered, and the amount of humidity is determined by the ratio of the amplitude of the signal envelope at the output of the sensor element on the surface acoustic waves and the amplitude of the signal envelope at the output of the reference device on the surface acoustic waves.EFFECT: improvement of operation speed in measurement of humidity.1 dwg
