Filed: 1983-12-23
Abstract: PURPOSE:To obtain a portable small-sized device while improving its sensitivity by forming the coil of a transmitting circuit in a plane shape and making it sensitive to the influence of the dielectric constant of water, and utilizing vairation in stray capacity with the water of the transmitting coil. CONSTITUTION:The Hartley circuit of a transmitter 2 is provided with the plane coil 1 having high inductance. A transmitted signal is inputted to a high frequency and amplitude limiter circuit 3 and an FM detecting circuit 4 and amplified by an amplifier 5, whose output is displayed on display devices 6 and 7. In this case, water has a large dielectric constant and large effective resistance, so the plane coil 1 which is influenced easily by water is provided and included in the transmitting circuit 2. Therefore, when this coil 1 is put close to a body to be measured, the stray capacity across the coil 1 increases with the dielectric constant of water and the oscillation frequency decreases. Thus, the moisture detector is composed of a small number of circuit parts and is reduced in size and weight, and has high sensitivity performance.
