Abstract

PURPOSE: To enable measurement of minute water content quantity by winding a detecting coil at the tip end part of an insulated bar and providing a transmission antenna around the periphery of the coil.
CONSTITUTION: The antenna is inserted in the central part of an insulating tube 5, and a detecting coil is wound around the tip end part. The ambient medium and coil are insulated with a cover 3 such as teflon or the like. A current is applied to the antenna by an oscillator 1 which generates a frequency the same as the resonance frequency determined by the electrical characteristics between the antenna position and the coil, and the variation of the water content around the senser is read out through the coil in an ammeter or voltometer 2. Accordingly, the minute quantity of the water content can be measured.
