DIFF Subgroup
G01K 11/32 using changes in transmittance, scattering or luminescence in optical fibres
Introduced: January 1995
Full Title
Full titles differ between systems:
IPC:
Measuring temperature based on physical or chemical changes not covered by group , , , or > using changes in transmittance, scattering or luminescence in optical fibres
CPC:
Measuring temperature based upon physical or chemical changes not covered by groups G01K3/00, G01K5/00, G01K7/00 or G01K9/00 > using changes in transmittance, scattering or luminescence in optical fibres
IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
IPC defines codes here since 2021.
