Abstract

The corrosion of related electric field is an important exposure source of warships in sea water, the spread distance of low frequency part can be several kilometers in the sea water, which has a promising application prospects in aspects of remote detection and development of underwater weapon fuze. However, because the sea water has a strong attenuation effect on the electric field signal, it makes the low frequency signal of warships quite weak, the useful signals are often as low as mV level or even V level. Therefore, it is of great significance to research on the low frequency weak signal detection sensor of warships. This paper selects the Ag/AgCl electrode for performance test after comparing several electrodes, and the test results show that the Ag/AgCl electrode has good performance on reversibility, Can respond to the change of electric field in time. The low frequency impedance of Ag/AgCl electrode is small, and has good performance on on the electrochemical. Ag/AgCl electrode has low self-noise at low frequency, the range potential changes at 0.3mV and the range fluctuation in 24 hours is less than 0.1mV, which meets the detection requirements to low frequency weak electric field signal of warships.
