METHOD AND SYSTEM FOR DETERMINING SERIES OF TEMPERATURE VALUES OF SOLDER BATH Russian patent published in 2024 - IPC G01J5/00 G01J5/02 G01J5/821 

FIELD: measurement technology.

SUBSTANCE: present invention relates to a method and a system for determining a series of at least two values of temperature of a solder bath 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 the temperature of the solder bath varies between measurements. According to the disclosed proposal, there is provided a set of data relating the predicted values of temperature T_pred of the solder bath with the corresponding MP measurement profiles. Providing a model F(t) describing the change in temperature of the solder bath over time, and future moment of time t(n) is selected and value of temperature T_pred(n) of solder bath is predicted for moment of time. MP measurement profile is selected and the selected MP(n) measurement profile is used at time t(n) to obtain a measured temperature value T_mes(n). Calculating the predicted temperature T_pred(n+1) of the solder bath and selecting the MP(n+1) measurement profile, corresponding to predicted temperature T_pred(n+1). Selected measurement profile MP(n+1) is used at time t(n+1) to obtain measured temperature T_mes(n+1).

EFFECT: higher accuracy of measurements.
