Industrial platinum resistance thermometers and platinum temperature sensors
IEC 60751:2008 specifies the requirements and temperature/resistance relationship for industrial platinum resistance temperature sensors later referred to as 'platinum resistors' or 'resistors' and industrial platinum resistance thermometers later referred to as 'thermometers' whose electrical resistance is a defined function of temperature.
Values of temperature in this standard are in terms of the International Temperature Scale of 1990, ITS-90. Temperatures in degrees Celsius are denoted by the symbol t, except in Table 1 where the full nomenclature t90/°C is used.
The standard covers resistors or thermometers for all or part of the temperature range 200 °C to +850 °C with different tolerance classes, which may cover restricted temperature ranges.
This second edition cancels and replaces the first edition published in 1983, amendment 1 (1986), and amendment 2 (1995). It constitutes a technical revision.
The significant technical changes with respect to the previous edition are as follows:
