Abstract
A probe for an egg-testing device includes a probe tube with an annular magnet disposed at a bottom end thereof. In the probe tube, a spherical excitation member is magnetically retained by the annular magnet. The probe is axially movable in a metal tube around which a bobbin is wound. In a rest position, the probe is retained by the magnetic attractive force between the metal tube and the annular magnet. The probe is brought into an operating position by an excitation pulse supplied to the bobbin, which pulse is provided by a control unit, taking into account the diameter of an egg to be tested and the conveying speed of a conveyor.
