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 ?t (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 ?t; and the receiver comprises a circuit for subtracting from the reception instant (T0) according to the reference time base, the time difference (?t) transmitted via the transmitter so as to give the differen
