Made in Saratov — import-substituting technology for rail flaw detection.

As a result of fruitful cooperation with the Volga Railway in NPP "Inter" import-substituting production technology developed highly sensitive and low-noise piezo-electric transducer (probe) for rail flaw detection with improved to 2-3 major parameters — the sensitivity and the noise level. Especially in the early days of 8-12 microseconds. Made probes can detect defects in the early stages of development. Have a minimum spread of the parameters from the best to the worst in the party, the stability characteristics of the time in service, especially in the winter, or at high temperatures.

  • Import-substituting sensors for inspection.
  • Import-substituting sensors for inspection.

Thirty years in Russia failed to improve the quality of piezoelectric transducers (PETs) to improve the reliability of rail flaw detection. AEDs for Russian Railways bought in "RDM" Moldova. Task set by my brother (who worked deputy. Chief Volga then. Roads) — make 2-3 times more sensitive and less rustling. Developed, received three patents for inventions, participated in three exhibitions at the Exhibition Centre, awarded Medal Exhibition Center, participated in three international exhibitions and forums, "Electronics-Transport 2008, 2010 years." in the World Trade Center Moscow, a diploma and a silver medal 3 Saratov salon of innovations and investments. Published in the trade journal "The path and track facilities" № 1, 2005

  • Diploma and silver medal Saratov interior innovation.
  • Diploma and silver medal Saratov interior innovation.

As a result of R &D, manufacturing 5500 units. AEDs handed over 4,000 units. on the Volga Railway and successfully production tested, signed bilateral instruments of positive test results and the achievement of the desired characteristics.
