Embodiment Construction

[0025] Such as figure 1 As shown, the conductivity sensor of the present invention includes a cylindrical insulating housing 1, an electrode 2, an insulating block 3, and a circuit board 4. The housing 1 is provided with a mounting hole 5 in the axial direction, and the cross section of the mounting hole 5 is circular or regular polygon. Three insulating blocks 3 and two electrodes 2 are arranged in the mounting hole 5 at intervals, and an annular first sealing gasket 11 is arranged between adjacent electrodes 2 and insulating blocks 3. The insulating block 3 and the electrode 2 are respectively provided with axial through holes corresponding to each other, and the axial through holes penetrate to form a flow channel 6. The two ends of the shell 1 are respectively screwed with an inlet connector 7 and an outlet connector 8. The channels in the inlet connector 7 and the outlet connector 8 communicate with the flow channel 6 in the shell 1, and the inlet connector 7 and the outl...
