PRINCIPLE OF OPERATION

SMD-300 principle of operation is based on eddy current

pulses analysis.

That current, known as Foucault currents, are originated in

metallic items from the outside pulse magnetic field.

Pulse magnetic field is formed by two transmitting coils housed

in a round Sensor body. Foucault currents are arisen in a part of

the metallic body that is closer to the sensor and is under the

influence of the coils.

Foucault currents magnetic field is captured by receiving coil

of the sensor and processed by build-in



Dedicated algorithm is used for this purpose.

The analysis results are displayed on a built-in LCD in a digital

or graphic mode on operator‟s preference.

Corresponding audio signal can be heard in the headphones as

well. The tone and loudness of it are adequate to the signal

level received.

SDM-300 operation is available by means of Control unit with

indication panel. All operational modes and the data obtained

are displayed on a build-in LCD.
