Title:
MOISTURE DETECTING SENSOR
Document Type and Number:
Japanese Patent JPS6038647
Kind Code:
A
Abstract:
PURPOSE: To detect moisture with good sensitivity, by arranging a hydroscopic substance between electrodes comprising different metals, and measuring a current flowing by the spontaneous electromotive force between both electrodes.
CONSTITUTION: A hygroscopic substance 4 is arranged between electrodes 1, 3 comprising different metals, for example, stainless steel and Zn and a current flowing by spontaneous electromotive force between both electrodes 1, 3 is measured by an ammeter 5. Moisture is detected from a calibration curve between current value and water content with good sensitivity.
