of piezo-resistive devices

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Measuring steady or quasi-steady pressure of a fluid or a fluent solid material by electric or magnetic pressure-sensitive elements; Transmitting or indicating the displacement of mechanical pressure-sensitive elements, used to measure the steady or quasi-steady pressure of a fluid or fluent solid material, by electric or magnetic means > by making use of variations in ohmic resistance, e.g. of potentiometers > of piezo-resistive devices

CPC:

Measuring steady of quasi-steady pressure of fluid or fluent solid material by electric or magnetic pressure-sensitive elements ; Transmitting or indicating the displacement of mechanical pressure-sensitive elements, used to measure the steady or quasi-steady pressure of a fluid or fluent solid material, by electric or magnetic means (measuring differences of two or more pressure values G01L13/00; measuring two or more pressure values simultaneously G01L15/00) > by making use of variations in ohmic resistance, e.g. of potentiometers > of piezo-resistive devices

Of 1 combined children, 0 exist in both systems.

1 codes are CPC-only extensions.
