SU1381329A1 - Angular displacement differential transformer transducer - Google Patents

Abstract

The invention relates to a measuring technique, the purpose of which is to improve the accuracy of a transformer angular displacement sensor by linearizing its conversion characteristic. The sensor contains a fixed magnetic core 1, formed by two parallel open circular branches and two saddle-shaped jumpers 2, and a Z-shaped ferromagnetic rotor 3, at the ends of which the sections of the measuring winding 4 are placed. - water 1. The magnetically conductive parts of the sensor form a symmetrical magnetic bridge, the balance of magnetic fluxes in which is disturbed when the angular position of the rotor changes 3. 2 silt

Claims (1)

Claim A transformer of angular displacement sensors, comprising a fixed magnetic circuit formed by two open circular branches mounted coaxially and parallel to one another and connected by a cross-shaped ferromagnetic element, an excitation winding, a ferromagnetic rotor and a measuring winding placed on it, characterized in that, for the purpose of increasing the measurement accuracy by increasing the linearity of the conversion characteristics, the field winding and the measuring winding are made in two sections and, the rotor is made in the form of a Z-shaped element, at the ends of which sections of the measuring winding are placed, the cross-shaped ferromagnetic element is made in the form of two saddle-shaped jumpers covering the axis of rotation of the rotor, which connect the ends of the annular branches of the stationary magnetic circuit located on opposite sides of this axis and on which field winding sections are placed.
