Abstract

The utility model discloses a plug-type permanent magnet flow transmitter, which consists of a copper axis cable, a copper tube, a stainless steel casing, a polar detecting body, a permanent magnet body, a magnetic field detecting coil, a positive electrode, a negative electrode, a lead board, a masking shield, a coil support, a plastic piece, and an intelligent part; the flow transmitter is mainly used in the flow measuring field; in addition to the simple structure, the small volume, and the low cost, the flow transmitter uses the permanent magnet body as the key component, changes and sets parameters by detecting the permanent magnet body and the electrode performance, increases the measurement precision, and has a very important significance.

Description

A kind of plug-in permanent magnet flow transmitter

Technical field

The utility model belongs to the flow measurement field, particularly mechanical component and magnetic cell, sensing, information transmission technology association area.

Background technology

What generally use at present is electromagnetic flow transmitter, be to utilize on the tested measuring point to fixedly mount flowmeter, establish the insulation lining by flange at inner-walls of duct, relative position is installed pair of electrodes on pipe side wall, coil is installed in the pipeline outside, delivers to converter by the information that electrode and coil produce.Can show fluid flow, and this complex structure, power consumption is big, cost is high, and is not easy to assemble, gives and produce and use is made troubles.

Summary of the invention

For solving the problem that above-mentioned technology exists, technical problem to be solved in the utility model provides in a kind of direct insertion pipeline, utilize permanent magnet and electrode, be not subjected to the pipeline restriction to measure a kind of plug-in permanent magnet flow transmitter of fluid data, the utility model is simple in structure, measurement is accurate, volume is little, cost is low.

The technical scheme that the utility model technical solution problem is taked is, the contrast accompanying drawing, describe, Fig. 1, the utility model is by coaxial cable 1 among Fig. 2, copper pipe 2, stainless steel casing 3, polarity detection bodies 4, permanent magnet 5, magnetic field detection coil 6, positive and negative electrode 7, wire guide plate 8, barricade 9, coil brace 10, working of plastics 11, intelligence part 12 is formed, wherein positive and negative electrode 7 is fixed on the wire guide plate 8, the coaxial cable 1 that is enclosed within 2 li of copper pipes also is fixed on the wire guide plate 8, barricade 9 is at the upside of wire guide plate 8, support 10 is 6 of permanent magnet 5 and magnetic field detection coils, working of plastics 11 is near permanent magnet 5, polarity detection bodies 4 is in the upper end of the utility model product one side, stainless steel casing 3 is in the outside, described a kind of plug-in permanent magnet flow transmitter, it is characterized in that, permanent magnet 5 is " E " shape (seeing accompanying drawing 2), and the shape at its two poles of the earth, outside all becomes miter angle with level.

The utility model compared with prior art, the beneficial effects of the utility model are: adopt permanent magnet, can make power consumption little, but powered battery, water quality requirement is lower, can use " E " shape of permanent magnet for a long time, the magnetic leakage of magnet is significantly reduced, the precision height, it is little, simple in structure to wear and tear, cost is low, plays positive effect from many aspects.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is the utility model product scheme of installation.

Fig. 2 is the utility model product A-A diagrammatic cross-section.

1. coaxial cables among the figure, 2. copper pipe, 3. stainless steel casing, 4. polarity detection bodies, 5. permanent magnet, 6. magnetic field detection coil, 7. positive and negative electrode, 8. wire guide plate, 9. barricade, 10. support, 11. working of plastics.

Embodiment

Positive and negative electrode 7 is fixed on the wire guide plate 8, the coaxial cable 1 that is enclosed within 2 li of copper pipes also is fixed on the wire guide plate 8, barricade 9 is at the upside of wire guide plate 8, and support 10 is 6 of permanent magnet 5 and magnetic field detection coils, and working of plastics 11 is near permanent magnet 5, detect polarity body 4 in the upper end of the utility model product one side, stainless steel casing 3 is in the outside, and described a kind of plug-in permanent magnet flow transmitter is characterized in that, permanent magnet 5 is " E " shapes, and the shape at its two poles of the earth, outside all becomes miter angle with level.

When permanent magnet 5 produces magnetic field, when positive and negative electrode 7 detects the water Semi-polarity, produce electromotive force, by the coaxial cable 1 that is fixed on the wire guide plate 8 corresponding signal is passed to intelligent part 12, magnetic field detection coil 6 detects permanent magnet 5 magnetic situations, receive intelligent part 12 by lead, thereby change the calculating parameter of intelligent part 12 according to the magnetic situation of change of permanent magnet 5, play the purpose of accurate measurement, polarity detection bodies 4 detects positive and negative electrode 7 polarity situations, receive intelligent part 12 by lead, thereby change the setting of intelligent partial parameters, play the purpose of accurate measurement according to positive and negative electrode 7 change in polarity.
