FIELD: automatics, measuring technology; may be used for measurement of rotational speed and for conversion of information by phaseometric methods for measurement of flow rate and torque. SUBSTANCE: magnetic system of pickup is fitted with Ж-shaped pole pieces and signal windings on jumpers-cores. Extreme pole pieces are positioned above teeth of ferromagnetic tooth inductor at distance of odd number of tooth pitches and central ones - above slots between teeth. :-shaped arrangement of pole pieces provides for series-opposed communication of magnetic flux inducing by this summary emf in windings of pickup with their series-opposed connection. The latter gives windings property of protection against action of fields of external noise. EFFECT: expanded application field, improved operational stability and reliability. |
