Inductive sensor and method of manufacturing an inductive sensor

Abstract: An inductive sensor and to a method for manufacturing an inductive sensor is provided. The inductive sensor comprises a winding body, an induction coil made of a high-temperature resistant metal alloy and wound onto the winding body, and a metal casing at least partially surrounding the induction coil. Here, the induction coil is compressed with metal oxide powder inside the metal casing.

Electronic transducer for transducing pressure values of industrial process fluids

Abstract: An electronic transmitter for transmitting pressure values of industrial process fluids comprising an inductive sensor employing a measuring diaphragm (M) movable as a function of the pressure changes in the process fluids, so as .to produce corresponding changes in inductance and therefore corresponding signals which are suitably processed in an associated electronic circuit. The measuring diaphragm is provided with a rigid center (N) forming or carrying one or more elements (38,40) of a material exhibiting high magnetic permeability.

A Method for Measurement of Nonferrous Particles Sizes in Lubricant Oil Independent of Materials Using Inductive Sensor

Abstract: Machine operating conditions can be obtained through lubrication oil detection; solid metal particles are the primary factor causing mechanical wear. The surface of the friction pair is usually specially treated with the nonferrous metal protective coating. Therefore, there are many kinds of nonferrous particles in the lubricating oil. In this paper, a method for measurement of nonferrous particles sizes independent of materials using the impedance signal of the inductive sensor is presented. Both the imaginary part and real part of the coil impedance signal are studied in this paper, which is different from traditional inductive sensor research only the imaginary part of impedance signal output is considered. Through theoretical analysis, it is found that the real and imaginary parts of coil impedance changes with different materials at the same size are corresponding to an elliptic function. Combining with the coil impedance measured in the experiment, the particle size can be obtained, which is independent of particle material.
