Abstract: Disclosed is a “factor 1” and inductive sensor device including an LC resonant circuit powered by a suitable generator, an operational chain of units for acquisition by sampling and processing of the response signal, and a functional set of units for evaluating at least one temporarily set value of the processed signal and supplying detection or non-detection information. The acquisition and processing unit includes analog a unit for filtering and/or amplifying the sampled response signal, and a unit for compensating the temperature drift of the response signal by correcting the sampled signal following the digital conversion thereof, associated with or including a temperature sensor.

Abstract: These results show that these two packagings are suitable The invention relates to a packaging for a liquid product containing yeast, that comprises at least one pervious material having an exchange surface S such that the ratio S/M is of at least 1.2, with S in cm2 and M being the mass of the liquid product in g, and having an O2 permeability coefficient CP of between 200 and 9000 cm3/m2.24 h.bar, and/or the O2 permeability coefficient CP ranging from 800 to 45000 cm3/m2.24 h.bar. The invention also relates to the use of such a packaging for containing a liquid product containing yeast. The invention further relates to a preservation method and to the use of a liquid product containing yeast.
