Сенсор магнітної індукції

Abstract

The magnetic induction sensor concerns a control equipment. The sensor consists of a direct voltage source, which through resistances supplies a bipolar double-collector magnetic sensitive transistor. A dual-gate FET and a bipolar transistor combined with a capacity and an inductance compose a generator of electrical generation. An oscillating circuit is formed of a parallel connection of the capacity based on the bipolar double-collector magnetic sensitive transistor, the dual-gate FET, the bipolar transistor and the inductivity. The technical result is a transformation of the magnetic induction to a frequency, that causes rising of a sensibility and a precision of measurements of the magnetic induction.
