Thermocouples

Thermocouple Polynomial Equations.

TYPE tuples are coefficients for converting T in Celsius to millivolts. INVERSE tuples are coefficients for converting millivolts to T in Celsius. First two values in tuple indicate lower and upper limits of equation validity, in Celsius for TYPE tuples and in millivolts for INVERSE tuples.

nupylab.utilities.thermocouples.calculate_temperature(millivoltage: float, tc_type: str, cold_junction_temp: float = 23) → float

Calculate temperature with cold junction correction.

Parameters:

  • millivoltage – measured reading in millivolts.

  • tc_type – thermocouple type.

  • cold_junction_temp – cold junction temperature in Celsius.

Returns:

corrected thermocouple temperature in Celsius.

Raises:

  • ValueError if millivoltage or cold_junction_temp are outside applicable TC –

  • range. –

nupylab.utilities.thermocouples.calculate_voltage(temperature: float, tc_type: str, cold_junction_temp: float = 23) → float

Calculate measured voltage with cold junction correction.

Parameters:

  • temperature – hot junction temperature in Celsius.

  • tc_type – thermocouple type.

  • cold_junction_temp – cold junction temperature in Celsius.

Returns:

measured voltage in millivolts.

Raises:

  • ValueError if temperature or cold_junction_temp are outside applicable TC –

  • range. –

nupylab.utilities.thermocouples.convert_to_temperature(millivoltage: float, tc_type: str) → float
