Type S Thermocouple

Type S Thermocouple
Data and Polynomial


  • Description
    Pt(10%)-Rh / Pt
  • Data source
    National Institute of Science and Technology (NIST)
  • Raw Data
  • Octave format
  • Curve fit
    • mV -> temperature (C)
      e is maximum error (in degrees C)
      v1 andf v2 partition the domain into three segments, each with a polynomial fit
      c is vector of coefficients: a10, a9, ... a0
      Note: Each column of c corresponds to one range (<v1,v1 to v2, >v2)

      e = 0.14051
