Abstract
The utility model provides an electromagnetic flow transducer which has simple structure, easy manufacture, low cost and high sensibility. The electromagnetic flow transducer is characterized in that a transducer body(comprising a measuring tube and an adapting flange) and an outer shell are manufactured with plastic, and the transducer body and the outer shell are formed in one time with injecting or molding method. No cockamamie mechanical process is needed, and the manufacture is very convenient. The cross-section of the measuring tube adopts a rectangular structure, so that the magnetic fields generated by the upper and the lower two energizing coils in the measuring tube are uniform and coincident. The diverging effect of the edge of the magnetic field is reduced to the lowest, and the measuring sensitivity of the instrument is effectively improved.
Description
Technical field
The supporting composition electromagnetic flowmeter of electromagnetic flow transducer and electromagnetic flux converter belongs to the industrial automation instrument field, and the utility model is specifically related to the architecture advances and the simplification of electromagnetic flow transducer.
Background technology
Electromagnetic flowmeter can be used for measuring the volumetric flow rate of various conducting liquids and liquid fixed double phase flow, thereby use extremely wide, but traditional electromagnetic flow transducer structure more complicated, the effective stainless steel of general measure is made, again with wear-resisting electric insulating medium linings such as neoprene or urethane rubbers, electric welding joint flange or the like, processing technology is loaded down with trivial details, production cost height, price factor have influence on the large scale application of electromagnetic flowmeter in some technical field.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easily manufactured, with low cost, highly sensitive electromagnetic flow transducer.
For achieving the above object, the technical scheme that adopts is, a kind of electromagnetic flow transducer comprises at least one pair of potential electrode and two field coils, it is characterized in that sensor body (comprising measuring tube and joint flange) and shell all adopt the plastics manufacturing in (comprising lid and bottom), with injection moulding or die pressing one-shot forming.
For improving the measurement sensitivity of instrument, the xsect of the utility model measuring tube adopts rectangular configuration, and the basic uniformity in magnetic field that the interior field coil up and down of measuring tube is produced is reduced to the influence of dispersing at edge, magnetic field minimum.
The beneficial effects of the utility model are that electromagnetic flow transducer is simple in structure, and the injection moulding mold pressing is easy to process, production cost is low, and rectangle measuring tube internal magnetic field is even, the measuring accuracy height.
