Table 8-1 summarizes the piecewise linear coefficients for each temperature segment. The appropriate set of

coefficients can be selected based on the temperature range of interest to achieve improved accuracy.

Table 8-2 provides representative transfer values, including nominal values based on Equation 1, calculated

piecewise linear values derived from Table 8-1, and lookup values based on averaged measured data.

The nominal transfer function provides a simplified implementation for systems that do not require enhanced

accuracy. For improved system-level accuracy, the piecewise or measured lookup values can be used

depending on system requirements.

The values in Table 8-2 are rounded for clarity. A complete lookup table derived from averaged measured data is

available in the ISOTMP35R product folder .

Note

For applications that do not require enhanced typical linearity correction, the nominal transfer function

shown in Equation 1 can be used across the full operating temperature range.
