КИПиА: температура Версия 1.5

This application serves as an analog to calibration tables for resistance thermometers and thermocouples.

The application consists of two parts. The first part is designed for use with resistance thermometers, based on GOST 6651-2009 GSI "Resistance transducers made of platinum, copper, and nickel." The metrological characteristics normalized within this part apply to the sensitive elements of resistance thermometers when connected directly to their leads, as well as to the thermometers when connected to the terminals of the head according to the manufacturer's schematic. If the resistance value of the internal wires is indicated on the body of resistance thermometers with a two-wire configuration, this value should be subtracted from the measured resistance.

The second part is intended for work with thermocouples, utilizing GOST R 8.585-2001 GSI "Thermocouples. Nominal static transformation characteristics." The EMF values of thermocouples as a function of the temperature at their hot junctions are calculated using polynomial approximations based on user-defined temperatures at their free ends.

Correction for cold junction temperature is calculated considering that the voltage measurement is performed with a potentiometer. When using a millivoltmeter, additional errors may occur due to the device's inherent power consumption.

This application is provided for informational and reference purposes only, and does not have legal force or applicability alongside regulatory documents in paper form.

I welcome any suggestions for further applications in the field of instrumentation and control systems (ICS).
