| description | Magnetic testing is one of the most widespread types of the
NDT. When carrying out magnetic testing various analog
magnetic measuring sensors are used: ferroprobe, based on
Gauss and Hall effects, etc.
A perspective direction of research in the field of nondestructive testing and technical diagnostics is the
development of measuring transducers with a digital output
signal, or a signal easily convertible into a code.
The paper considers magnetic transducer based on the
oscillistor effect, which has a threshold nature and involves
the appearance of electric current oscillations, flowing
through a semiconductor sample, placed in the longitudinal
electric and magnetic fields. The results of experimental
studies of the dependence of the threshold electric field
strength on the magnetic field strength are presented.
The scheme of the converter of magnetic field induction
into the impulses of electric voltage, and diagrams of its
work are given.
The sensitivity of the converter depends on the frequency
of the sample frequency generator and the conversion
coefficient of the ramp generator. |
