An analog calibration tables for resistance thermometers and thermocouples.

The application is an analog calibration tables for resistance thermometers and thermocouples.

  The application consists of two parts. The first part of the application is designed to work with resistance thermometers. This was used to GOST 6651-2009 GSI "Thermal resistance of platinum, copper and nickel." The metrological characteristics, normalized in accordance with this program, apply to RTD sensors connected directly to their terminals and resistance thermometers when connected to the terminals of the head in accordance with the scheme specified by the manufacturer. If the body resistance thermometers with a two-wire circuit is set to the internal resistance of the wires, it must be subtracted from the measured resistance value of the resistance thermometer.

  The second part of the application is designed to work with thermocouples. This was used to GOST R 8.585-2001 GSI "Thermocouples. Nominal static characteristics of conversion." TEDS values ​​of thermocouple, depending on the temperature of the working end at the free ends of a customized application designed for polynomials approximating these dependencies.

 The amendment to the temperature of the cold end is calculated based on the fact that the voltage is measured by a potentiometer. If the measurement is used millivoltmeter, the error occurs because of the device's own power consumption.

  This application is a reference and information and has no legal force and can not be used on a level with the regulations on paper.

  I will be glad to hear new requests for applications from the field of instrumentation.
