TUSCAn

Makes available functions for:

• ITS-90 compatible temperature sensors (Standard Platinum Resistance Thermometers), allowing:
  • Retrieval of reference resistance ratio W_R from t_90R reference temperature
  • Retrieval of reference temperature t_90R from W_R reference resistance ratio
  • Given sensor coefficient's: sub-range, R_tpw, a, b, c, d, W₆₆₀, c₁, c₂, c₃, c₄, c₅
    • Retrieval of t₉₀ temperature from sensor's resistance res
    • Retrieval of res resistance from sensor's t₉₀ temperature.
• IEC 60751 compatible temperature sensors (Platinum Resistance Thermometers), allowing:
  • Retrieval of reference resistance res_R from t_90R reference temperature
  • Retrieval of reference temperature t_90R from res_R reference resistance
  • Given sensor coefficient's: R₀, A, B, C
    • Retrieval of sensor's resistance res from t₉₀ temperature
    • Retrieval of temperature t₉₀ from sensor's resistance res
• IEC 60584 compatible temperature sensors (Thermocouples), allowing, for a given type:
  • Retrieval of reference voltage emf_R from t_90R reference temperature
  • Retrieval of reference temperature t_90R from reference voltage emf_R
  • Given sensor coefficient's: a, b, c, d
    • Retrieval of sensor's voltage emf from t₉₀ temperature
    • Retrieval of temperature t₉₀ from sensor's voltage emf
