First Claim
1. An item of equipment for logging and transmitting measured values of physical magnitudes, comprising:
- at least one standalone measurement sensor configured to measure a plurality of the values of physical magnitudes, the sensor being powered by an electric cell and comprising a transmitter configured to transmit at determined intervals at least one of the values measured by the sensor,and a receiver for collecting the values transmitted by the transmitter, wherein;
the sensor comprises a means for measuring a temperature in the vicinity of the cell to obtain a temperature value as one of the values of physical magnitude, wherein the measured temperature relates to the ambient temperature immediately next to the sensor,a link is provided to supply to the transmitter the measured temperature value, which transmitter is configured to transmit the at least one of the measured values, which includes the measured temperature value, at the determined intervals,and the receiver is configured to;
receive and store each measured temperature value,establish a cell temperature profile as a function of time only from the stored measured temperatures,compare the established cell temperature profile with a plurality of predetermined typical temperature profiles, each predetermined typical profile having an upper temperature threshold, a lower temperature threshold, and a time period, the upper temperature thresholds being different from each other, the lower temperature thresholds being different from each other, the time periods being different from each other, and each time period representing one of a plurality of predetermined life spans for typical cells, to identify a first of the predetermined typical temperature profiles, the first of the predetermined typical temperature profiles having the time period which is longest amongst the predetermined typical temperature profiles for which the cell temperature profile remains between the respective upper and lower temperature thresholds, anddetermine a date of replacement of the cell based only on the time period of the first of the predetermined typical temperature profiles.
