Probe, inrichting en werkwijze voor het testen van eieren.

摘要

A probe (30) for an egg-testing device (1) comprises a probe tube (31) with an annular magnet (34) disposed at a bottom end (32) thereof. In the probe tube (31) a spherical excitation member (50) is magnetically retained by the annular magnet (34). The probe (30) is axially movable in a metal tube (11) around which a bobbin (14) is wound. In a rest position, the probe (30) is retained by the magnetic attractive force between the metal tube (11) and the annular magnet (34). The probe (30) is brought into an operating position by an excitation pulse supplied to the bobbin (14), which pulse is provided by a control unit (200), taking into account the diameter of an egg (3) to be tested and the conveying speed (v) of a conveyor (110).
