Full Title

Full titles differ between systems:

IPC:

Measuring temperature based on the expansion or contraction of a material > the material being a solid > constrained so that expansion or contraction causes a deformation of the solid > the solid body being constrained at more than one point, e.g. rod, plate, diaphragm

CPC:

Measuring temperature based on the expansion or contraction of a material (G01K9/00 takes precedence; giving other than momentary value of temperature G01K3/00) > the material being a solid > constrained so that expansion or contraction causes a deformation of the solid > the solid body being constrained at more than one point, e.g. rod, plate, diaphragm (G01K5/62 takes precedence)

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
