ANALYZER PULSED MAGNETIC MULTIPARAMETER I-


PURPOSE

      The IMA-M (MA-M) pulsed magnetic multiparameter analyzer is designed for nondestructive testing of hardness of articles in machine-building, produced of medium-carbon and alloyed steels after volumetric hardening, after low-temperature, medium-temperature and high-temperature annealing.

OPERATION PRINCIPLE

      The operating principle of the IMA-M Analyzer consists in local magnetization of the article under test by series of varying in amplitude and direction pulses of magnetic field, induced by superimposed solenoid, in measurement of the parameters of the magnetic hysteresis loop on the gradient of the normal component of the residual magnetization field strength and in transforming them to the values of hardness on the in advance created multiple correlation connection.

CONSTRUCTION

      The device IMA-M is designed as a portable one consisting from the electronic unit and the transducer, connected by the electrical cable with the length of 1,5 meters.
