Piezoelectric units

Piezoelectric units (PU) are intended for operating together with the electric units of RDM series flaw detectors. PU are used in the sounding circuits for reveling flaws in one or two railway lines, and in the elements of railway points and junction rails.
PU are the components of the mechanized system of the ultrasonic testing and consist of resonators, mounted in a special trunk and fixed on a resistant foundation. The units are equipped with the contact fluid- delivery system.
