The utility model solves the problem of magnetism leakage, has the advantages of simple structure and small size, and enlarges the application range.
Description
Technical field
The utility model relates to electrochemical analytical instrument, particularly a kind of electromagnetic type conductivity sensor.
Background technology
Measure the conductivity of solution with electromagnetic induction principle, utilize the electromagnetic induction between two magnetic core coils and the detected solution exactly, promptly after drive coil adds ac-excited voltage, its magnetic core produces an alternating magnetic field, the detected solution of two magnetic core coils is considered as an equivalent coil if will flow through, the exchange current that induces of this equivalent coil makes the magnetic core of inductive coil produce an alternating magnetic field again so, same this alternating magnetic field can induce an alternating voltage (electric current) on its coil, this alternating voltage is directly proportional with the equivalent coil exchange current, promptly is directly proportional with the conductivity of detected solution.But the leakage field of drive coil magnetic core can produce an alternating voltage equally on inductive coil, influenced the linearity of measuring.Existing electromagnetic type conductivity sensor is taked two vertically arranged methods of coil are solved the leakage field problem, but the complex structure of this sensor, and volume is bigger, has limited the usable range of sensor.
Summary of the invention
Existing sensor bulk is big, the little existing technical matters of use face in order to solve for the utility model, and a kind of electromagnetic type conductivity sensor with metallic shield is provided.
According to above-mentioned purpose, the utility model provides a kind of electromagnetic type conductivity sensor, comprises drive coil, inductive coil, is characterized in: also have becket, sheet metal; Wherein between drive coil arranged side by side and inductive coil, clamped becket, sheet metal has been arranged in its periphery packing; Wherein becket, sheet metal are connected with ground wire.
The utility model makes simple in structure, the volume-diminished of electromagnetic type conductivity sensor owing to taked above technical measures, has enlarged usable range.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in the figure, drive coil 1, the inductive coil 3 of coated insulation material again after evenly being wound with certain number of turn enamel-cover copper wire on two toroidal cores, its end face is relative side by side, therebetween is equipped with becket 5, in two coil peripheries packing sheet metal 7 is arranged, being fit into the centre of being made by resistant material again has in the shell 9 of through hole.The lead-in wire 6 of the lead-in wire 2 of drive coil 1, the lead-in wire 4 of inductive coil 3, becket 5, the lead-in wire 8 of sheet metal 7 are drawn from shell 9, wherein go between and 6 be connected with the ground wire of apparatus measures circuit with lead-in wire 8, can play the effect of magnetic shielding effectively, make leakage field drop to minimum point.During measurement, to immerse with the sensor of shell 9 sealings in the detected solution, solution in shell 9 mesopores constitutes the flow of solution loop with solution all around, promptly form the equivalent coil of flow through drive coil 1, inductive coil 3,2 add an ac-excited voltage from going between, then can 4 record an ac induction voltage (electric current),, can measure the conductivity of detected solution by the processing of apparatus measures circuit from going between.This electromagnetic type conductivity sensor simple in structure, volume is very little, both can be placed in the bulk container and measure, and also can be directly installed in the pipeline and measure, and has enlarged usable range.
