Detailed Description

EGU class for performing RTD (Resistive Temp Device) conversions.

Actual equation is:

C = ( R/(R+C0) - 1/(C2) ) * C1

C0 (C C2 + C1) R = - ----------------- C C2 - C1 C2 + C1

Temp = ( R + C4 ) / C5

Nominal C0 = 1820 Nominal C1 = 4096 (Exact) Nominal C2 = 3

Fitted from +/- 100 degree data from 0118MF literature from Goodrich (manufacturer) Fitted C3 = - 1994.5 Fitted C4 = 7.9051

Member Function Documentation

__init__ (  coeff0  , coeff1  , coeff2  , coeff3  , coeff4  , units  = "" )

Initialize a raw/EGU linear conversion object. Parameters: coeff[0-4]  One of the coefficients of the function. See function doc units  The engineering units name, e.g. 'cm'

egu (  rawValue   )

Convert a value in raw units to engineering units Parameters: rawValue  Value in raw units Returns: Engineering units value after the conversion.

raw (  eguValue   )

Convert a value in engineering units to raw units Parameters: eguValue  Value in engineering units. Returns: Raw value after the conversion.
