Type B
Type B Thermocouple
Type B Thermocouple
Data and Polynomial
- Description
Pt(30%)-Rh / Pt(60%)-Rh
- 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 = 26.625
v1 = 0.43700
v2 = 1.8220
