Abstract
1. Способ повышения чувствительности электромагнитных датчиков пульсаций скорости преобразователей гидрофизических полей, включающий нанесение платиновой черни на торцевые поверхности платиновых электродов, установленных в зазорах магнитной системы датчика, заподлицо с их внешней поверхностью, отличающийся тем, что перед нанесением платиновой черни электроизоляционный материал датчика покрывают дополнительным слоем электроизолирующего материала, инертного к соляной, азотной и платинохлористоводородной кислотам, при этом толщину дополнительного слоя выбирают исходя из возможности обеспечения блокировки диффузии примесей из компаунда в процессе платинирования электродов.2. Способ по п.1, отличающийся тем, что нанесение дополнительного слоя электроизолирующего материала на диэлектрическую поверхность производят последовательно с первоначальным нанесением его на всю поверхность датчика и последующей механической очисткой торцевых поверхностей электродов.3. Способ по п.1 или 2, отличающийся тем, что дополнительный слой электроизолирующего материала выполняют толщиной не менее 5 мкм.4. Способ по п.1 или 2, отличающийся тем, что в качестве дополнительного электроизолирующего материала используют полипараксилилен или фторэпоксидный лак.5. Способ по п.2, отличающийся тем, что перед нанесением дополнительного слоя электроизолирующего материала в торцевых поверхностях измерительных электродов выполняют лунки.6. Способ по п.5, отличающийся тем, что лунки выполняют глубиной 0,2-0,3 мм.1. A method of increasing the sensitivity of electromagnetic sensors of pulsations of the velocity transducers of hydrophysical fields, including applying platinum black on the end surfaces of platinum electrodes installed in the gaps of the magnetic system of the sensor, flush with their outer surface, characterized in that before applying platinum black, the insulating material of the sensor is coated with an additional layer electrically insulating material inert to hydrochloric, nitric and platinum chloride acids, with thicknesses the additional layer is selected based on the possibility of providing blocking diffusion of impurities from the compound during platinized elektrodov.2. The method according to claim 1, characterized in that the application of an additional layer of insulating material on the dielectric surface is carried out sequentially with the initial application of it on the entire surface of the sensor and subsequent mechanical cleaning of the end surfaces of the electrodes. The method according to claim 1 or 2, characterized in that the additional layer of electrically insulating material is made with a thickness of at least 5 microns. The method according to claim 1 or 2, characterized in that as an additional electrically insulating material, polyparaxylene or fluoroepoxy varnish is used. The method according to claim 2, characterized in that, before applying an additional layer of electrical insulating material in the end surfaces of the measuring electrodes, holes are made. The method according to claim 5, characterized in that the wells are 0.2-0.3 mm deep.
