Известно применение в качестве материалов дл призм электроакустических датчиков различных твердых веществ, например органичеокаго стекла, полиформальдегида, поликапронлоктана и других. Однако одни из этих материалов , например органическое стекло, обладают невысокой износостойкостью и относительно небольшим коэффициентом затухани ультразвуковых колебаний. Другие наоборот , име хорошую износостойкость, .как например поликапронлоктан, не обладают достаточной прозрачностью, что очень важно дл визуального контрол за смачиванием контактной грани искател .It is known to use electro-acoustic sensors of various solids, such as organic glass, polyformaldehyde, polycapron octane, and others, as materials for prisms of electroacoustic sensors. However, some of these materials, such as organic glass, have low wear resistance and a relatively small attenuation coefficient of ultrasonic vibrations. Others, on the contrary, having good wear resistance, such as polycapron octane, do not have sufficient transparency, which is very important for visual monitoring of wetting of the contact face of the searcher.
Предлагаемый в качестве материала дл призм электроакустических датчиков поликарбонат прозрачен и негигроскопичен. Износостойкость и коэффициент затухани в нем ультразвуковых волн почти в три раза выше, чем у органического стекла.The polycarbonate offered as a material for prisms of electroacoustic sensors is transparent and non-hygroscopic. The wear resistance and attenuation coefficient of ultrasonic waves in it is almost three times higher than that of organic glass.
