AJL500 Ampoule Injection Electronical Micropore Leak Inspector

Application

The machine is dedicated to inspect Ampoule, vial and oral liquid products for possible liquid leakage. It can inspect pinhole and cracks on those bottles.

Parameters

Working principle

Infeed conveyer belt takes inspected containers to infeed wheel for equidistant separation. Feed track takes container to deliver screw , then turn it over 90°to level to reach different inspection station. Inspection consists of many stations, it can inspect different position according to customer requirement and finally separate qualified and unqualified products automatically by the reject unit.

Voltage principle

V is high frequency high voltage power, its two ends is separately connected with emitting electrode and receiving electrode. C₁ and C₂ are capacitance between electrode and solution (Because of the cut off by isolated bottle surface, electrode can not contact solution, then form capacitance). R is solution resistance. When no leak present on container, the generated induction current is defined as I₁. When container is leaked, the capacitance between bottle surface and electrode will disappear, capacitive reactance generated by capacitance is zero, the return circuit will generate higher current I₂. Compare the current value to judge if the container is leaked.
