VIBRATION METER Russian patent published in 1997 - IPC

FIELD: vibration measurement. SUBSTANCE: vibration meter includes SHF generator, detector with indicator connected to it and antenna. Distance from antenna in the form of round waveguide to detector is found from relation , where l₁- is distance from antenna to detector; λ_w is length of wave in transmission line; n - 1,3,5..., and distance from antenna to tested object is determined from relation , where l₂ is distance from antenna to tested object; λ_o- is length of wave in free space. Length of round waveguide along transmission line is established from relation , where l₃ is length of round waveguide along transmission line and radius of round waveguide is found from relation . EFFECT: increased precision of vibration meter. 4 cl, 3 dwg, 1 tbl
