  • the separation of the static and dynamic components and the extreme amplification of the latter before transmission makes it possible to significantly improve the information that we can hope to use after measurement.
  • the separate transport of the static component and the dynamic component amplified 300 times makes it possible to hope for a signal to noise ratio 300 times higher after transmission.
  • this dynamic component is subsequently processed by a digital assembly, it is a non-negligible increase in the resolution which the technique of separation of the static and dynamic components of the signal allows.
  • the static and dynamic components are separated downstream of the collector to reduce the number of collector rings and thus the volume and the cost of the device.
  • the device thus produced corresponds to a reduced bulk, to a minimum number of parts and to optimum security and quality of measurement.
  • the presence of as many line amplifiers as there are channels to be transmitted upstream of the connectors (90) makes it possible to improve the characteristics of the signals transmitted and in particular to reduce the noise level of the transmission, in particular when the equipment are getting old.
  • the protection stages provided either at the level of the output stages, that is to say after the line amplifiers or at the level of the input stages of the power supplies protect the equipment against the hazards of the site or more simply against interference from lightning or the switching of large electrical machines nearby.
