COERCIMETER -1


PURPOSE

      The coercimeter -1 is designed for nondestructive testing of the quality of the heat treatment, mechanical properties and structure of the articles of metallurgy and machinebuilding of ferromagnetic steels on the established correlation between the measured coercive force value and the parameters under test.

PRINCIPLE OF OPERATION

      The tested article is magnetized using the horseshoe electromagnet, the is magnetized in a reverse sense on the descending branch of the hysteresis loop. At the instant of the equality to zero of the magnetic flow in the circuit the superimposed electromagnet - the article the value of the demagnetization current is measured, that proportional to the coercive force of the material is.
      The correlation between the measured value of the coercive force and the parameters under test is determined using the standard 30415-96.

CONSTRUCTION

      The coercimeter -1 is designed as a portable one consisting from the electronic unit and the transducer (including the horseshoe electromagnet), connected by the electrical cable with the length of 1,5 meters.

250

Overall dimensions, mm:

- electronic unit

385x265x140

- transducer

122x75x85

The digital indication is in A/m
There is the option of computer indication of the measured value

      The use of nondestructive testing of the commercial articles using the coercimeter -1 instead the direct measurement of mechanical properties helps to save the metal and to enhance the productivity of the testing process and to ensure the high quality of the articles.
