Inner Pressure Inspection
by Induction
Oscillograms deriving by the induction analog measurements of two different lids. Each oscillogram composed by the sequence of hundredths of individual samplings operated by a single-channel analog sensor. A symmetric one representing an actually closed can. An asymmetric one, representing a leaking can whose inner pressure is low. Passing one and the same can closed by a lid, through the same Inner Pressure Inductive Inspection a statistically significative number of times, i.e. 1000 times, results in 1000 slightly different oscillograms. From a layman point of view, differences representing the superposed effect of physical properties of the object, measurement instrument and medium, changing during the 1000 tests. Differences making sense of the way IGUSes (further details about IGUS, here) observe the state space where the entire description of the object exists.
Oscillograms deriving by the induction analog measurements of two consecutive different Aluminium Foils (“alufoils”), typically used to seal the containers of Sensitive Beverages or Pharmaceuticals. Well visible how superior result the values of induction at the outside of the same analog detector seen before

Optic Closure Presence inspection, with analog photosensorsIntroductionThe optic closure inspection, with analog photosensor, is one of the simplest inspections existing. It adopts an analog photosensor, with a projector irradiating passing closures by the top and a receiver giving out to an operational amplifier a signal whose extension, the duration counted in encoder pulses, is proportional to the reflection. …
