Summary:monitoring technique, possibly testing of electrophysical parameters of railway road objects. SUBSTANCE: apparatus includes matrix-type eddy current converter in the form of n oscillating loops with temperature stabilizing circuits made as monolytic structure impregnated with compound; detector unit; unit for processing signals of converter and registration unit. Novelty is n temperature pickups, n filters designed for passing low frequency information signal and encapsulation envelope of elastic dielectric material applied onto surface of converter structure. Outlets of temperature pickup are connected with mean points of temperature stabilizing circuits of oscillating loops of converter; inlets of filters are connected with outlets of oscillating loops of converter and outlets of filters are connected with inlets of detectors. EFFECT: enhanced degree of protection against outer influence caused by random dynamic processes. 1 dwg
