PRT Calc
~~~~~~~~~~
PRT Calc is intended as an aid for anyone who uses platinum resistance
thermometers. It will calculate the resistance of a PRT at any temperature
within the specified range or will calculate the temperature if the
resistance is known. PRT Calc can, therefore, be used by people calibrating
or designing platinum resistance thermometers based on BS 1904, or people who
wish to use PRT sensors directly into a DVM or bridge without any intervening
electronics.
The formulae used by PRT Calc were derived from the British Standard
BS 1904 : 1984, for which full credit is acknowledged. The formulae should
give no errors greater than the least significant digit in the BS tables,
hence ensuring that any results obtained by this program can be considered to
be correct for all practical purposes. (If anyone discovers any errors PLEASE
let me know).
