FIELD: measurement technology.
SUBSTANCE: invention relates to a method and a system for determining a series of at least two values of temperature of a soldering bath with using a device, containing cable with fiber-optic core and detector. Method according to the present invention has been shown to be particularly suitable for a plurality of repeated measurements, during which it is required to achieve final temperature of soldering bath. According to the declared proposal, a model F(t) is provided, which describes the change in the temperature of the soldering bath over time; determining critical value Tcri of temperature; temperature Tmes(n) of the soldering bath is measured at time t(n). Further, approximated rate Rheat(n) of heating is determined on the basis of model F(t), critical value Tcri of temperature and measured value Tmes(n) of temperature. Determining the time tcal(n + 1) based on the temperature difference ΔT(n) between the temperature critical value Tcri and the temperature measured value Tmes(n) and the approximated heating rate Rheat(n) and temperature Tmes(n + 1) of the soldering bath is measured at time tcal(n + 1).
EFFECT: high accuracy of the obtained data.
