Abstract

System for transmitting data for remote logging between a measurement sensor (1a, 1b) comprising an electronic circuit with non-synchronized internal clock and a memory for storing at least one value measured at a first instant (t₁), and a transmitter (7) suitable for transmitting at a second instant (t₂) the value or values measured at the first instant (t₁), and a receiver (12, 12a) synchronized to a reference time base, for gathering the measured values transmitted; the sensor (1a, 1b) comprising an electronic circuit suitable for establishing the time difference Δt (t₂−t₁) between the instants of transmission (t₂) and of measurement (t₁) according to the internal clock of the sensor, and the transmitter (7) transmits, with the value or values measured at the first instant (t₁), this time difference Δt; and the receiver comprises a circuit for subtracting from the reception instant (T₀) according to the reference time base, the time difference (Δt) transmitted via the transmitter so as to give the difference (T₀−Δt) as date to the measurements transmitted.
