PICKUP FOR MEASURING CORROSION ACTIVITY OF FLUID Russian patent published in 2007 - IPC G01N17/04 

FIELD: measuring technique.

SUBSTANCE: pickup comprises housing made of wall and bottom, flat permanent magnet mounted inside the housing, two flat induction coils, and sensor that is made of conducting material and can be in a contact with the corrosion liquid. One of the planes of the flat permanent magnet is in a contact with the housing bottom. The dielectric material is interposed between the second plane of the flat permanent magnet and first induction coil and between the second induction coil and sensor. The flat induction coils are separated with a dielectric. The pickup has cylindrical sleeve provided with the flange, two detachable locking members, and ring spacer made of insulating chemically stable material. The flat induction coils, dielectric and dielectric material that separates the flat permanent magnet and induction coils are made in block and represent a single cylindrical module. The dielectric and dielectric material are made of a chemically stable insulating sealing member. The first side of the flange of the cylindrical sleeve tightly abuts against the housing bottom, and the second side tightly abuts against the first locking member. The inner diameter of the cylindrical sleeve is equal to the outer diameter of the flat permanent magnet and single cylindrical module. The first surface of the sensor tightly abuts against the outer bottom of the cylindrical sleeve. The first side of the ring spacer tightly abuts against the sensor, and the second surface of the ring spacer tightly abuts against the second locking member. The flat permanent magnet and housing bottom are provided with through axially aligned openings that receive wires of the flat induction coils that pass out of the single cylindrical module. The housing and locking members are made of a chemically stable material.

EFFECT: expanded functional capabilities and enhanced reliability.
