Abstract

1,078,176. Electrophysical measurement. TESLA, NARODNI, PODNIK. Sept. 29, 1965 [Oct. 13, 1964; May 21, 1965], No.41332/65. Heading G1N. In an arrangement for measuring an electrical quality of a substance by measuring the damping effect it produces on a tuned circuit, the search coil, together with a compensating coil, are housed in a conductive screening can be made of aluminium, copper or silver, which may also include a 5 microns thick aluminium "window" (Fig. 2) and/or a ferrite sleeve (Fig. 3). The internal diameter of the can is to be not more than five times the outer diameter of the search coil, and its wall thickness is to be greater than three times the penetration depth of the electromagnetic field of the search coil due to skin effect.
