Embodiment Construction

[0024] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0025] The invention uses an inductive probe as a seawater conductivity measurement unit, adopts two circular magnetic rings coaxially arranged, and the outside is covered with a corrosion-resistant insulating material, and the inner holes of the two magnetic rings are used as a solution channel. When performing measurement, an AC current is passed into the excitation coil of the excitation magnetic ring, and according to the principle of electromagnetic induction, a corresponding alternating magnetic flux is generated in the excitation magnetic ring, so that an induced current is generated in the measured solution loop, which is manifested as crossing the The current loop that excites the magnetic ring and the output magnetic ring, and this current loop generates alternating magnetic flux in the output magne...

Description

technical field [0001] The invention relates to the technical field of seawater detection, in particular to an anti-pollution CTD conductivity probe. Background technique [0002] The anti-pollution CTD is equipped with underwater fixed platforms such as submersible buoys, buoys, and seabed bases for long-term online observation. Anti-pollution and anti-bio-adhesion designs are required to achieve self-capacitance measurement functions. [0003] Although the traditional electrode conductivity sensor has high measurement accuracy, it is extremely susceptible to pollution from marine organisms, oil and sediment, resulting in signal distortion, performance degradation, and shortened service life of the instrument. Contents of the invention [0004] In view of the above deficiencies, the present invention proposes an anti-pollution CTD conductivity probe, which adopts inductive conductivity measurement. The inductive conductivity probe is robust and reliable, not afraid of co...
