Dielectric constant-type resistance-insensitive direct-reading water content meter

摘要: A dielectric constant-type resistance-insensitive direct-reading electrical apparatus for measuring water content wherein a circuit coupled to coil of tank in highfrequency oscillator through mutual induction coefficient Mo comprises series connection voltage pickup coil, taking out detected voltage, main and first variable capacitor. second capacitor Ce is connected the junction between said respective values Ce, are suitably chosen maintain particular relation among constants so that phase deviation due test sample parallel with may be discriminator without influence resistive component sample.
