Research of parameters of razdel'no- of the combined transformers is conducted depending on material of acoustic delays - prisms: from quartz glass TOSP is easily soiled, poliimidaimida PEI 1000. Technology of making of acoustic and electric screens of transformers is improved with the purpose of diminishing of the mutual influencing radiative and receiving p'ezoplastin. Experimental research of influencing of sizes and form of p'ezoplastin, heights of prisms, is conducted on the level of signals of vermin, conditioned superficial waves. On results researches the contact separately-combined transformers of series of P-112 are made for ultrasonic tolschinometrii, which provide: on frequency 10 Mhz measuring of thickness in a range 0,6 - 80 mm at the radius of curvature of the controlled surface no less what 2 mm; on frequency there is 5 Mhz is a range ot 1 to 300 mm at the radius of curvature more than 5 mm Product Description popup.authors popup.nrat_date 2020-04-02 Close
