Abstract
An inspection machine for pressure testing a glass bottle filled with water. A normal test pressurizes the bottle until the pressure reaches an acceptable level. If the bottle bursts or leaks the pressure will not reach the acceptable level. A control monitors the pressure curve and can determine when a bottle bursts. The control can also determine that a leak is present and when the leak happens with “N” successive bottles, the control indicates that there is a maintenance problem.
