G01K 7/22 the element being a non-linear resistance, e.g. thermistor (G01K7/26 takes precedence)
Introduced: September 1968
Title
Titles differ between systems:
IPC: the element being a non-linear resistance, e.g. thermistor
CPC: the element being a non-linear resistance, e.g. thermistor (G01K7/26 takes precedence)
Full Title
Full titles differ between systems:
Measuring temperature based on the use of electric or magnetic elements directly sensitive to heat > using resistive elements > the element being a non-linear resistance, e.g. thermistor
Measuring temperature based on the use of electric or magnetic elements directly sensitive to heat (giving results other than momentary value of temperature G01K3/00) > using resistive elements > the element being a non-linear resistance, e.g. thermistor (G01K7/26 takes precedence)
CPC subdivides this area 3x more granularly than IPC with 2 additional codes.
2 codes are CPC-only extensions.
