In this paper, based on the eddy current transducer the automated system for continuous monitoring of quality of work hardening of metal cylindrical products in real time is developed. For the construction of this system the standard high-precision measuring equipment which is connected to the personal computer by means of the software-controlled interface was used. On the basis of presence of correlation between the electromagnetic properties of metals and their structural state the method of noncontact control of depth of mechanical deformation of surface of product is offered. The generalized normalized informative parameter is chosen and on it basis the noncontact method for determining the depth of surface hardening is developed. The rational algorithm for operation of the system, based on the limit test of parameters of depth of the hardened layer, which takes into account the totality of measuring and accounting operations and provides specified metrological characteristics, is resulted.
